Longer thoughts from @david_shane

Links I liked, July 19-25 (Bicycle Physics, Hungry Cleaner Shrimps, Family Bikes)

1. The Bicycle Problem that Nearly Broke Mathematics

Terrible headline here, but pretty cool story that goes to show that just because a device is very common, doesn’t mean it is well understood.  A couple snips:

In April 1970, chemist and popular-science writer David Jones demolished this theory in an article for Physics Today in which he described riding a series of theoretically unrideable bikes. One bike that Jones built had a counter-rotating wheel on its front end that would effectively cancel out the gyroscopic effect. But he had little problem riding it hands-free.

This discovery meant that there was no simple rule-of-thumb that could guarantee that a bike is easy to ride. Trail could be useful. Gyroscopic effects could be useful. Centre of mass could be useful. For Papadopoulos, this was revelatory. The earliest frame builders had simply stumbled on a design that felt OK, and had been riding around in circles in that nook of the bicycle universe. There were untested geometries out there that could transform bike design.

2. Trump: Tribune of Poor White People

Everyone was passing around this piece of political/cultural analysis last week – give it a read if you haven’t seen it, any excerpt can’t do it justice.  But I’ll drop one anyway:

The “why” is really difficult, but I have a few thoughts.  The first is that humans appear to have some need to look down on someone; there’s just a basic tribalistic impulse in all of us.  And if you’re an elite white professional, working class whites are an easy target: you don’t have to feel guilty for being a racist or a xenophobe.  By looking down on the hillbilly, you can get that high of self-righteousness and superiority without violating any of the moral norms of your own tribe.  So your own prejudice is never revealed for what it is.

3. What Happened With the Library Millages

This is a local story but… I bet this sort of thing happens all the time.  City passes millage specifically for library that should increase their “intake” by about $2,000,000 – but actual intake only increases by about $250,000 because the city decreases the amount of money given the library from the general fund.  There is an obvious incentive here to pass specific millages for popular programs (like the library), to free up more general fund money for less popular stuff.  Be aware…

4. A Brief Word to J.I. Packer on His 90th Birthday

Thomas Aquinas died at age 49.  John Calvin and Jonathan Edwards died at 54.  Charles Spurgeon at 57.  Martin Luther at 62.

5. Facebook Messenger Hits 1 Billion Users

There is nothing deep and complicated about this article just… whew.

More than 10% of voice over IP (VoIP) calls occur on Messenger, and 17 billion photos are sent on the app each month. And interactions with businesses have risen sharply. People now exchange 1 billion messages with businesses every month, a figure that has more than doubled in the past year.

6. Heavy Boots

To prove my point, we went back to our dorm room and began randomly selecting names from the campus phone book. We called about 30 people and asked each this question: 1

1. If you’re standing on the Moon holding a pen, and you let go, will it
a) float away,
b) float where it is,
or c) fall to the ground?

About 47 percent got this question correct. Of the ones who got it wrong, we asked the obvious follow-up question:

2. You’ve seen films of the APOLLO astronauts walking around on the Moon, why didn’t they fall off?

About 20 percent of the people changed their answer to the first question when they heard this one! But the most amazing part was that about half of them confidently answered, “Because they were wearing heavy boots.”

7. Cleaner shrimp stuffing his face at feeder ring

OK personal video here – I don’t know how common this is, but our cleaner shrimp has learned that me opening the top of our saltwater aquarium means food is coming, and he’ll now run up and over to the feeder ring and start grabbing food!  On the plus side his actions help the sinking food sink, which I suppose the other fish appreciate.

 

8. This man rescued a bear from the jaws of a cheese puff bucket

Man sees bear with cheese puff bucket on head.  Man lassos bear.  Man and bear roll around on the group together for a couple minutes (but bear cannot bite man because cheese puff bucket).  Bear gives up and climbs tree, man ties rope to tree, calls authorities to come help bear.

9. Taga 2.0: The Ultimate Most Affordable Family Bike

At the risk of totally getting sucked in by advertisement… this seems like a pretty awesome idea.

10. As More People Get High in Colorado, More Kids Head to the Hospital

By itself, not an argument against legalization perhaps, but legalization proponents like to pretend there is no downside, and that needs to be pushed against.

Although cannabis poisonings in children are not common, the incidents have definitely increased following Colorado’s legalization of recreational use in 2012. The rate of increase in hospital visits is considerable—it doubled between 2009 and 2015—but the overall numbers remain small: 1 child per 100,000 people before legalization and 2 children per 100,000 people after legalization. Numbers of poison control center calls, though still small overall, increased by more than five times.

Links I liked, July 11-18 (Alzheimer’s proteins, Pokemon in a rationalist world, “Uniformed Lives Matter”)

After a long hiatus, maybe I’ll start this up again.  There has just been too much good stuff to read of late.

1. Physicists discover how proteins in the brain build-up rapidly in Alzheimer’s

Obvious good news here as far as perhaps a path toward treating the disease by limiting the fibril replication.  Stargate fans might feel a chill at the ending.  :)

Dr Saric also argues that the findings could be of great interest in the field of nanotechnology. “One of the unfilled goals in nanotechnology is achieving efficient self-replication in manufacturing of nanomaterials. This is exactly what we’ve observed happening with these – if we’re able to learn the design rules from this process, we may be able to achieve this goal.”

2. Life on the line in Venezuela as economic crisis worsens

Sad to see this country collapsing, especially now knowing some people from it.  And I feel like that collapse is being underreported though I pay so little attention to mainstream media sources now it’s hard for me to tell for sure.  Life itself becoming of less value.  What an intro:

The robbers demanded a cellphone from a 25-year-old in black shorts. Instead of handing it over, Junior Perez took off toward the entrance to the pharmacy. Eight shots rang out, and he fell face down.

The dozens of shoppers in line were unmoved. They held their places as the gunmen went through Perez’s pockets. They watched as thick ribbons of blood ran from the young man’s head into the grooves of the tiled walkway. And when their turns came, each bought the two tubes of rationed toothpaste they were allowed.

3. Why Companies Have To Be People, Constitutional Amendment Or No

Disagreements don’t bother me (at least not very much).  Slogans that short-circuit thought bother me a lot – “corporations aren’t people!” is one such slogan.

In the jargon we’ve got two types of people. We have natural persons. That’s you and me and all the other humans wandering around. Then we also have legal persons. That’s corporations, partnerships (in certain cases), sports clubs, unions and on and on and on.

The really crucial point here is that the law, the responsibilities of the law, only apply to “people”. So, if we want unions, clubs, corporations, to be able to use the law then they must be people. Sure, they’re not natural people, they’re not humans, but they must be some form of a person in order to be a legal person who can then use the law. If you cannot use the law then you cannot sign a contract. Perhaps more importantly you cannot be sued. And perhaps even more importantly you cannot be taxed if you are not a person, natural or legal.

4. Michigan senator to introduce ‘Uniformed Lives Matter’ bill

This article is over a week old, but I bring it up because the governor of Texas today said he would like to sign a similar bill there, making attacks on police officers a hate crime.  I’m against the idea inasmuch as I’m against the existence of the category of “hate crimes” period – I have yet to hear of the murder motivated by love.  Is it worse to engage in violence again someone because you hate them because of their race, than because you hate them because of their profession, or because you just hate Bob Smith?  I’d say no, and we would do well to drop that distinction, which muddles our thoughts and public discourse in many other ways as well.  If we’re not going to drop that distinction, of course the number of groups covered by such laws is only going to go up, and up, and up.

5. Chicago on the Brink: A retreat from proactive policing has unleashed mayhem in the city.

Good long read about the crime-boom, and why it has boomed, in Chicago.

Since the shooting of Michael Brown in Ferguson, Missouri, in August 2014, the conceit that American policing is lethally racist has dominated the national airwaves and political discourse, from the White House on down. In response, cops in minority neighborhoods in Chicago and other cities around the country are backing off pedestrian stops and public-order policing; criminals are flourishing in the resulting vacuum.

Officers who try to intervene in this disorder face a virulent street situation, thanks to the current anti-cop ideology. “People are a hundred times more likely to resist arrest,” an officer who has worked a decade and a half on the South Side informs me. “People want to fight you; they swear at you. ‘Fuck the police, we don’t have to listen,’ they say. I haven’t seen this kind of hatred toward the police in my career.”

6. Pokemon Go in a fractured and flattened world

At the risk of making something fun and silly into something serious… probably actually some truth to this.

In a secular age, it is common for people to conceive of the world in terms of scientific cause and effect. We are less likely to be stunned by the magnificence of this world, and more likely to feel as if we are only cogs in a naturalistic machine. The secular mind, due to its rationalist foundation, must create meaning rather than discover it.

But suddenly, a game based on Japanese mythology invades the naturalistic machinery of the modern age. Pokémon envisions the world as if it were filled with kami that resemble the Greek gods of old. The creatures inhabit trees, rivers, and rocks, similar to the ancient Norse or Celtic myths that described a world teeming with fairies and elves. When you take the ancient myths that gave us fantastic animals such as centaurs and unicorns and place them within the animistic worldview of Shintoism, you start to see why the Eastern world of Pokémon feels both strange and familiar.

7. Can Michigan spend tax dollars on private schools? We’ve already said no.

My only comment is that inasmuch as the reason people are upset here is the thought that public funds might go to promote religious instruction – sorry, but the public schools themselves offer plenty of religious instruction these days. (Actually they always did, but it has become more evident as America has become more divided.)  There is no such thing as a worldview independent education – it matters a lot more in some fields than others, to be sure, but the public schools teach them all.  (Alas, I don’t think the governor is making his appeal on those grounds.)

Notes from Spring, 2016, MIAAPT Meeting

Below find my notes from the Spring 2016 MIAAPT meeting, held at Cranbrook, Bloomfield Hills, MI.  As always my notes are just my notes – accuracy is not guaranteed, and they reflect what I found interesting, not necessarily a good representation of what was actually said.

11139377_1076254549099467_3548274138335896401_n

Modeling Mechanics with Google Sheets, Don Pata

Talked about creating spreadsheets in Google Sheets to model (usually) kinematics behavior.  Two things that struck me in particular – when creating a graph that shows velocity as a function of time *with air resistance*, if the initial speed is greater than terminal velocity you see the object slow down as it falls, which students find intriguing.  Second, similar to LCC’s PHYS251 “Energy Conservation” lab they make an plot with experimental data showing a mass oscillating on a vertical spring, kinetic energy, potential energy, and total energy all plotted together as a function of time, total energy is just a flat line, looks beautiful.

Counterintuitive Results from Collisions Involving Rotations, Michael Faleski

He wrote a nifty app: http://websites.delta.edu/michaelfaleski/SpaceCollision.html , that allows you to collide a sticky object with a rod in space, with or without the pivot point of the rod fixed.  Results that surprised him – for certain arrangements of the pivot point and object, the center of mass of the system actually moves backwards after collision.  Second, if you want to maximize the angular velocity of the system after collision, you do NOT want the object to hit right on the end of the rod.  There is a give and take between the increased torque, and the increased moment of inertia, that makes the best collision point just a little closer to the pivot point.

Creating a Mental Model of a Radian, James DeHaan

When he asks his students to define a radian, their answers generally amount to either, “there are two pi of them in a circle” or “it is about 57 degrees”.  Talked about how a radian is really a non-arbitrary (unlike degrees) angle measure, the ratio of an arc length to a radius.

The Natural Human Electricity and its use to Operate Touchscreens, Wathiq Abdul-Razzaq

Said students think Physics labs are boring, there are no chickens hatching, we need to give them more exciting titles, like the title of his talk.  Said that when a human finger touches a touchscreen that amounts to a capacitance of about 100 pF.  Talked about a nifty demo where he physically wedges a battery between two (large) capacitor plates hooked to a voltmeter, then removes the battery, voltmeter reading does not change.  Talked about charging those plates from the static electricity of his students.

Experimenting with Impacts, Michael LoPresto

Talked about a simple lab they do in which they drop steel balls, of different masses and from different heights, into a tub of sand.  Students then measure the rim diameter of the ejected material.  They then plot the rim diameter on the y-axis, initial potential energy on the x-axis.  He cited a paper which showed that if most of the energy goes into ejecting the material the graph goes like E^1/4, whereas if most of the energy goes into digging the hole the graph goes like E^something_I_forget.  In any case students get something close to E^1/4.  A questioner mentioned that Purdue has an “Impact Earth” app that does similar theoretical calculations.

Cheap Sensors Allow for Real Questions, Steve Dickie

Talked about how the Maker Movement has resulted in many cheap analog sensors.  These sensors can actually be integrated with LoggerPro – you can purchase a Vernier cable with analog LabPro connector on one side, just loose wires on the other side, and attach your maker movement sensor.  LoggerPro will just record the voltage as a function of time, but you can add a calculated column to give the quantity you actually want.  They purchased some $30 accelerometers which they embedded in football helmets they then attacked with hammers.  In summary – sensors cheaper and more capable that a lot of the stuff you buy from Vernier.

Flipping a Class Without Flipping Out, Alan Grafe

Talked about the practical aspects of flipping a class.  Uses Notability for drawings, Camtasia for recording and editing.

How Standards Based Grading Improved Student Achievement, Joanna DeMars

Talked about assigning grades based on mastery of certain standards, rather than traditional grading.  Has 5-10 standards per unit, all standards are pass/fail, requires perfection for pass.  Subsequent reassessments get harder.  Has seen her AP passing rates go up, not sure how much of that is due to grading change.

Building a Culture for Learning Physics, Bryan Battaglia

“Failure is always an option.”  “Physics is not the most important thing.  Love is.” ~Feynman

Using Science Olympiad Events to Bring Engineering and Design Into the Classroom, James Gell

Talked about using SOINC events to help meet NGSS engineering standards, and how much students love these activities.  Especially talked about a boomilever design project, boomilever must hold 15 kg out at 40 cm, students building boomilevers with a mass of only 11 g that can do this.  At national SOINC masses get down to 6 g.

Why do we Teach Physics Like It’s 1899?, Vance Nannini

Students love space stuff.  Mentioned how much they love NASA “Seven minutes of terror” video about Curiousity lansing.  Talked about gravitational assists, elastic collision, inbound and outbound velocities of spacecraft same from perspective of the planet, from sun’s perspective outbound is much larger, planet orbit radius does shrink by a tiny amount.  Gravitational assist theory was developed in the 1920s.  “Suck less every day” his motto.

Physics of clustering and invasion of living cells, Evgeniy Khain

Hard to summarize the keynote.  Studies cancer cells from a theoretical perspective, with experimental partners who study the cells in petri dishes.  The cells will migrate their own diameter in 5-10 minutes – this is just a diffusive motion because they are in a fluid, so the distance they travel goes like the square root of time.  Time for cell division is about a day.

He specifically studies brain tumors – median survival time is about 12 months.  There are sort of three cell behaviors involved.  Cells in the inside of tumors don’t do much because they haven’t the room.  Cells on the edges of tumors have a rapidly dividing phenotype.  And then sometimes cells detach from tumors and have an invasive phenotype – for reasons not well known, the division rate of these cells falls by a factor of 10.  That might seem like a good thing, but the problem is radiation and chemotherapy target dividing cells, so the invasive cells are relatively invisible to those treatments.

He then developed a stochastic model to describe division, proliferation, and adhesion, in which cells begin at random locations in a 2-dimensional gridwork, and are then permitted to diffuse, divide, and stick together according to parameters chosen by the simulation.  Clusters of cells will form, or not, based on the adhesion parameter, but the surprise was there is actually a phase transition, a certain adhesion parameter at which, suddenly, cluster formation becomes possible.  This has also been verified experimentally.  If clusters do form, the phenotype of some cells will switch to proliferative, and a recurrence of the tumor may occur.

However, even if the adhesion parameter is too low spontaneous clustering can occur if enough cells “random walk into the same room”, and hang together for long enough (about an hour) for the phenotype to change.  In a 3 mm by 3 mm system this will happen in roughly 4 days.

Business Meeting

Fall meeting, which will be at LCC, will be coordinated with MSTA.  Teachers are interested in having higher ed help show them how to implement NGSS engineering standards.  One high school teacher mentioned he would love help putting together specific labs and projects.  The thought is that some long-term partnerships might form to this end.

Alex Azima, “We’re interested in stuff”.

Taoufik Nadji was elected new 2nd VP.

EHW and Reflections in Physics Curriculum, Taoufik Nadji

Talked about the need for student reflection on what they have learned, and this email reflection homework he has his students turn in every two weeks.  They must follow specific guidelines to reflect, question, and feel.  Reflect – summary of concepts they understood, must quote something from the textbook with page number and something from lecture.  Question – summary of concepts they would still like to understand.  Feel – a transfer summary of how they felt about what they learned, perhaps applying it to the rest of their life.

Circular Motion – Lo-Tech to Hi-Tech, Daniel Lorts and Frank Norton

Demonstrated a rotating platform they use to help teach rotation consisting of a 24″ lazy-susan base supporting a larger wooden circle.  First demo, put tube of fluid on circle, showed how angle of water depends upon location and speed.  Also attached a Vernier cart by rubber band, then spring scale, to get a measure of forces.  Did some neat demos where you lightly hold a ball on the rotating surface as well, then let it go.

Principles for Smart Teaching, Samanthi Wickramarachchi

Played a fun game to show that active learning aids memory.  Showed 14ish word pairs where, in seven cases, you had to think for two seconds to complete one of the words, in the other seven cases you were just given both.  Five minutes later people remembered better the word pairs they had to think about.

A Progress Report on the Physics Lab Curriculum Changes at Lawrence Tech, Changgong Zhou

At Lawrence, lab and lecture are still strictly divided, and the lab is only one credit – what does that say about how much we value lab work?  How much attention do instructors even pay to lab reports?  How much do students care when they only get them back two weeks after they do the lab?  They are trying to make changes so students do meaningful writing and get immediate feedback upon leaving lab, and also trying to make the labs less “do this, then this, then this…”.  Results have been good so far, students who get bad feedback even wanting to repeat parts of labs to improve their score.  He mentioned students lose 25% if they blow a fuse in lab!

A Case Study: Novel Group Interactions through Introductory Computational Physics, Michael Obsniuk

Talked about attempts to incorporate computational physics into introductory physics in an MSU course called “Projects and practices in Physics”.  The course involves a mix of analytic and computational methods.  Some students have no coding experience, so they use visual Python or are given minimally working programs they modify.  One example problem is a simulation of the motion of a satellite bound to the Earth.

Notes from Fall, 2015 MIAAPT Meeting

Links I liked, 8/10/2015 – 8/16/2015 (safe spaces, bad science, internet arguments)

Oh dear, I have been slacking on these lately.

1. The Coddling of the American Mind

OK, everybody on the internet has already linked this article – so if you haven’t read it yet, go do so. Too long to really quote, but essentially about what making colleges places of “trigger warnings” and “safe spaces”, where “microaggressions” are zealously hunted and punished, does to the way we think.

2. A Scientific Look at Bad Science

Another nice Atlantic essay on why an increasing amount of apparently bad science is being published.

3. There’s a sneaky trick that is allowing this biker to seemingly defy physics by driving on water

A free-body diagram! In a mainstream news article! (But is it correct?)

4. I Don’t Know if I’m Pro-Choice After Planned Parenthood Videos

As I’ve only realized lately, to be a man, and to declare yourself pro-choice, is to proclaim your neutrality. And, as I’ve only recently been willing to admit, even to myself, that’s another name for “wimping out.”

At least that’s how my wife sees it. She’s pro-life, and so she’s been tearing into me every time a new video is released. She’s not buying my argument that, as a man, I have to defer to women and trust them to make their own choices about what to do with their bodies. To her, that’s ridiculous—and cowardly.

Yes, someone unfriended me on Facebook because I shared this article, true story.

5. Whole Foods’ John Mackey: Why Intellectuals Hate Capitalism

I don’t watch a lot of video interviews. This was a good one. Made me order his book.

6. MY ID ON DEFENSIVENESS

Lot of ideas worth pondering in this essay.

People like to talk a lot about “dehumanizing” other people, and there’s some debate over exactly what that entails. Me, I’ve always thought of it the same was as Aristotle: man is the rational animal. To dehumanize them is to say their ideas don’t count, they can’t be reasoned with, they no longer have a place at the table of rational discussion. And in a whole lot of Internet arguments, doing that to a whole group of people seems to be the explicit goal.

7. Our Southern Mountaineers (1918)

Shot almost a century ago, this 1918 newsreel footage might possibly be the earliest known moving images of Appalachia.

Links I liked, 6/22/2015 – 6/28/2015 (recycling problems, teacher teachspans, ACLU)

1. American recycling is stalling, and the big blue bin is one reason why

Single-stream recycling is actually a big pain for processors.  And it results in a lot of waste – 1/3 of glass picked up is crushed in processing and has to be sent to landfills, perhaps contaminating other materials along the way.

2. Video of Portland tornado

Pretty dramatic footage of a tornado that went through downtown Portland, Michigan (we don’t get many up here!).  You wonder about that car that turned off-frame two seconds before it went through.  No one was killed, but that must have been one spooked driver.

3. Sermon: The Communion of Saints

Sermon from our church’s international ministry director.  Question he got from a Muslim student – “why do your imams try to drown you?”  (Baptism reference.)  He he.

4. Most Michigan Teachers Leave Before Qualifying For a Pension

Found this interesting not directly because of the pension part, but because I know that you must work 10 full-time years before becoming eligible for a pension.  Which means most Michigan teachers don’t work ten full-time years.  Huh.

5. SpaceX’s Falcon 9 Rocket Breaks Up During Launch Vehicle Failure

Video at link.  Second recent failed attempt to deliver cargo to the ISS.  Space travel is still more difficult than we often think.

6. ACLU: We’re only interested in protecting some civil rights

It continues to boggle my mind that merely declining to participate in an event (like a same-sex marriage) because you have a moral problem with it is “imposing your views on others”.  However compelling someone else to participate in such an event against their will, and suing them if they don’t, isn’t?  Exactly backwards, but the ACLU doesn’t get it.  (Ed Morrissey does, though.)

7. Gay Conservatism and Straight Liberation

Russ Douthat points out the irony that while Kennedy’s decision on gay marriage argues by placing marriage on a very high pedestal, most millenials seem to be rejecting that conception of the institution.  (But I don’t think they’ll object to the ruling.)  Good read for some historical perspective.

Three quick takeaways from a debate on money in politics at the Lansing Center this evening

Attended a highly educational (and respectful) debate about campaign finance at the Lansing Center tonight. No really, it was fun. Debaters were Bradley A. Smith (Center for Competitive Politics) and Rich Robinson (Michigan Campaign Finance Network). Video of the debate is already up if you want to take a look.  Three takeaways:

1. Both speakers were actually agreed on the point that minimum dollar amounts at which contribution disclosure becomes required are ridiculously low – apparently especially in Michigan where the first penny you donate to a political campaign is supposed to be properly reported and disclosed. (Robinson said this law was created in an attempt to break up Democratic bingo games.) One of the practical effects of this is that in low-budget campaigns, where someone running for township trustee might spend $800 in total to get elected, is that they look around, see how complicated it would be to take $5 and $10 donations from their neighbors, and say “forget about it, I’ll just pay for the whole campaign myself”. Thus in one very obvious way these laws discourage public participation in politics – is that what we want? Said Smith, it used to be that you’d announce your candidacy, then pass around the hat and get your first donations. Do that today and you’d be breaking about ten federal laws.

2. At one point came the question, “what would happen if we eliminated maximum contribution limits to political campaigns?”. Said Smith – sounds like a terrible idea, campaigns would be like, why, they’d be like pretty much every campaign in America before 1970. Is anybody out there rejoicing at how much less influence money has in politics today, vs. before 1970 when all these laws didn’t exist?

3. Smith’s opening illustration – nobody likes the idea of the federal government listening in on your phone calls, that’s not right. Suppose it was proposed that the government would keep a record of all your political activities, you would be required to report them, and then the government would make that list available to potential employers, ex-spouses, anybody that might have it in for you could get a look – would you be in favor of that law? But in fact we already have those laws, we call them campaign finance disclosure laws.

Links I liked, 6/15/2015 – 6/21/2015 (Bikes are great, Russian censors, Midwest earthquakes)

1. US mid-continent seismicity linked to high-rate injection wells

A new study pins the blame for the increase in Midwest earthquakes on, specifically, injection wells pumping more than 300,000 barrels of wastewater into the ground each month.  Apparently smaller rate injection wells have been used for decades without this issue.

2. InterVarsity Regains Access to Cal State Campuses

Absurd rule that religious organizations could not require their student leaders to share the same religion has been… clarified?  Overturned?  Can’t tell, but in any case, IV is back.  Discouraging statistic at the end though,

Just under half (44 percent) of evangelicals told LifeWay Research recently that student groups at public schools should not be allowed to require their leaders to hold specific beliefs.

3. Why Erasing Hamilton From The $10 Bill Is Erasing Our History

Not sure I buy the conspiracy, but Steve Forbes is one fire… and opposed to losing Hamilton from our currency.

4. Propaganda Cat Brings Soviet a Nazi Deserter

Enough said.  (From January 11, 1942.)

5. Why Freddy’s BBQ From ‘House Of Cards’ Couldn’t Really Exist

A case study in how regulators prevent good things from ever existing.

6. How we discovered the dark side of wearable fitness trackers

But in analysing these findings, we also started to notice that the relationship is perhaps not as pure and unproblematic as first believed. The idea that technology is both liberating and oppressive, first articulated by philosopher Lewis Mumford in the 1930s, started to shine through. When we asked the women how they felt without their Fitbit, many reported feeling “naked” (45%) and that the activities they completed were wasted (43%). Some even felt less motivated to exercise (22%).

7. Get Rich With… Bikes

The bike will probably turn out to be the best thing ever invented for humankind. It is taking us a while to realize this, but I think more people are coming around with each generation.

Links I liked, 6/8/2015 – 6/14/2015 (Red Cross, Hillsdale, Adoption Laws)

1. How the Red Cross Raised Half a Billion Dollars For Haiti and Built 6 Homes

Hold your charities accountable!  And know that the biggest and most mentioned are often not the best.

2. What Makes a Woman?

Fascinating article from a left-wing professor in the New York Times who is seriously upset by what the transgender movement is doing to our conception of womanhood.  To quickly summarize her position, essentially she argues that “what makes a woman a woman” is the process of growing up as and living as a woman, both in what that entails biologically and what results from cultural expectations. Ergo someone like Jenner, who has not lived that life, cannot just pop some pills and have some surgery and voila, he’s a woman with just as much a right to speak into feminine issues as someone like this author.  (She’s also rather ticked that Jenner proved his feminine credentials by effectively adopting every stereotype about women on the market.) Fascinating reading, especially coming from someone on the left.

Women’s colleges are contorting themselves into knots to accommodate female students who consider themselves men, but usually not men who are living as women. Now these institutions, whose core mission is to cultivate female leaders, have student government and dormitory presidents who identify as males.

3. Liberal Arts for Conservative Minds

An interview with the president of Hillsdale College.

One might wonder, given all this, whether Hillsdale manages to attract many Democratic-leaning students. “The college is not really about that. We don’t ask anybody about that,” Mr. Arnn says. “They tend to be conservative, but here’s why: If you’re going to read old books as if they might have an abiding value, already you’ve taken a step away from the Daily Beast.”

4. Tim Hunt: ‘I’ve been hung out to dry. They haven’t even bothered to ask for my side of affairs’

Cue again Kirsten Powers’ comment that have to stop reducing people to their least-popular political opinion – or in this case, bad joke.  Apparently being a Nobel Laureate is no protection from the social media mob.  Sad story.

5. Snyder, Legislature putting Michigan on path of intolerance and regression

The media just doesn’t get religion, case #4,248.  Somehow a bill that allows adoption agencies to follow the dictates of their conscience when operating (especially as regards placing children with single or same-sex parents) is limiting children’s “access to loving and stable forever homes”.  To the contrary, states that lack these conscience protections have seen Catholic and other adoption agencies lose state contracts – fewer people out trying to place kids in a home actually does harm them.  But once again, a government makes just the teeniest, tiniest nod in favor of religious freedom and the media hyperventilates.  And usually MLive is actually pretty decent, as big media outlets go.

And now something pretty.

3. The Rise Of Generic College, USA

Essentially an argument that college administrators prefer adjunct faculty to full-time faculty because that are much more amendable to doing whatever the administration wants.

4. I’m a liberal professor, and my liberal students terrify me

In 2015, such a complaint would not be delivered in such a fashion. Instead of focusing on the rightness or wrongness (or even acceptability) of the materials we reviewed in class, the complaint would center solely on how my teaching affected the student’s emotional state. As I cannot speak to the emotions of my students, I could not mount a defense about the acceptability of my instruction. And if I responded in any way other than apologizing and changing the materials we reviewed in class, professional consequences would likely follow.

A widely commented upon article this last week, if you somehow missed it.

6. The next wave of “body diversity”: Disabled by choice

The fact that someone sincerely desires something cannot be the full measure of what is good and appropriate.
