BehindTheMedspeak: "75% of med students are on antidepressants or stimulants (or both)"

Screen Shot 2019-01-05 at 1.41.55 PM

That's the provocative title of a 2017 article by Pamela Wible, M.D.

It generated an enormous response when I posted it on Hacker News last Saturday, quickly rising to the top of the home page:

I sent the article to my psychiatrist, whose practice includes medical students; he responded, "Yep. I believe it, mostly. Would estimate 50-66% but medical boards suppress self-reporting."

NASA's Deep Space Network

You know they're out there.

Now you can listen in live.

Enter.

From Wikipedia:

••••••••••••••••••••••••••

The NASA Deep Space Network (DSN) is a worldwide network of U.S. spacecraft communication facilities, located in the United States (California), Spain (Madrid), and Australia (Canberra), that supports NASA's interplanetary spacecraft missions.

It also performs radio and radar astronomy observations for the exploration of the solar system and the universe, and supports selected Earth-orbiting missions.

DSN is part of the NASA Jet Propulsion Laboratory.

Similar networks are run by Russia, China, India, Japan and the European Space Agency.

Most and Least Expensive Car Brands to Maintain

AAa

From YourMechanic:

••••••••••••••••••••••••••••••••••

We looked at which major brands cost the most to maintain over the first 10 years of a car's life.

We grouped all years of all models by brand to compute their median cost by brand.

Imports from Germany such as BMW and Mercedes-Benz, along with Cadillac, are the most expensive.

A Toyota is about $10,000 less expensive over 10 years, just in terms of maintenance.

Toyota is by far the most economical manufacturer.

Scion and Lexus, the second and third most inexpensive brands, are both Toyota subsidiaries.

Most domestic brands, like Ford and Dodge, are in the middle of the pack.

While luxury cars call for the most expensive maintenance, many budget vehicles rank relatively high.

Kia, an entry-level brand, surprises with maintenance costs 1.3 times the median. In this case, sticker prices don't represent maintenance costs.

samesamebutdifferent: Ship of Theseus

F22b1f35-8245-44b7-a64e-62d5c730ec78

From Wikipedia:

••••••••••••••••••••••••••••••

In the metaphysics of identity, the ship of Theseus is a thought experiment that raises the question of whether a ship — standing for an object in general — that has had all of its components replaced remains fundamentally the same object.

The Thought Experiment

First, suppose that the famous ship sailed by the hero Theseus in a great battle has been kept in a harbor as a museum piece. As the years go by some of the wooden parts begin to rot and are replaced by new ones. After a century or so, all of the parts have been replaced. Is the "restored" ship still the same object as the original?

Second, suppose that each of the removed pieces were stored in a warehouse, and after the century, technology develops to cure their rotting and enable them to be put back together to make a ship. Is this "reconstructed" ship the original ship? And if so, is the restored ship in the harbour still the original ship too?

The Wikipedia article goes on to discuss a number of resolutions (below).

What they carried: boj reader Scott dishes

Last week in a comment on the 4-color-pen throwdown post, he wrote:

•••••••••••••••••••••••••••••

I waded through graduate school with a BIC fine point 4 color (the one with the orange barrel), a bottle of Pentel correction fluid with a roller ball dispenser, and a pocket drafting template. I have kept some of those notes just to remind myself that I could once write neatly, use Einstein notation properly, and draw good free-body diagrams — I don't know what's happened since; likely migration to keyboards, mice, and screens.

•••••••••••••••••••••••••••••

You can too!

All you need are:

• BIC fine point 4-color pen — "the one with the orange barrel" (top)

• Pentel correction fluid

618CnsA9SpL._SL1200_

• Pocket drafting template

Attachment-1

The pen costs $8.99, the correction fluid $7.73, and the drafting template $5.81.

Bonus: if you buy all three, Scott will throw in his degree.
