Oh wow, if you like books maybe pick up a copy of my wife’s achingly beautiful novel about the love affair between Eleanor Roosevelt and Lorena Hickok?
Somehow I’ve lucked out and have an 8yo who thinks secretly reading under the covers past her bedtime is an act of rebellion, and it hasn’t yet occurred to her that her flashlights never seem to run out of batteries.
Let me explain one reason why this is a potentially serious problem.
First, you should know that when I search google from an incognito window it gives me the right answer: just shy of 14 billion years, the current scientific consensus among cosmologists and astronomers.
This means Google is using tracking info – what it thinks it knows about me – to decide which answer it should serve to a question *where there is clear scientific consensus on the answer*.
You can see the problem here.
The 6yo figured out she can sneakily stick a note on someone’s back. But she doesn’t know they should say things like “kick me,” so they just have space facts on them.
If, based on your browsing, google decides you are anti-vaccine, and you do a search about how to protect your kids from measles, how will it respond?
Will it present the medical consensus, or point you to a "study" that hasn't been around long enough for serious review?
What the Nobel Prize fails to mention here, and fails to mention every year, is that both Burnell and Hulse were 24 year old grad students when they made their discoveries. Hulse is a man, so he got the prize. But Burnell is a woman, so the prize was given to her supervisor.
Happy birthday to Russell Hulse who was awarded the
#NobelPrize
in Physics for discovering a new type of pulsar (word created from ”pulsating star”).
Coincidentally the first pulsar was also detected
#OTD
in 1967, by Jocelyn Bell Burnell.
Thanks to everyone who mentioned headlamps. We actually put one out where she'd see it, and she gave it a try, but she prefers her trusty LED flashlight.
Obviously google searches shouldn't take the place of advice from trusted experts like medical doctors, or, in the case of the age of the Universe, cosmologists.
But it also shouldn't make things worse in an attempt to show you what it thinks you want to see.
My 8yo has discovered Google Docs, and now instead of playing video games she is obsessed with word-processing and experimenting with different templates and making things like a resumé for our dog.
Now, there may be another explanation for why I am getting the wrong answer in a regular window, and the right one in an incognito window. I have a google scholar profile, so maybe it thinks I want to see new research.
But I don't like the idea of google giving one answer when it can see certain info about who I am, and a different answer when it can't, to a scientific question where there is definite consensus.
This Blade Runner-esque photo of Toronto is by Lucan Coutts. It's getting a lot of shares without acknowledging him as the photographer. Here's his instagram:
Or maybe this is just a coincidence, and repeated searches will give different answers as some other variable (location, etc) changes. I don't know, that's why I said "potentially" in the first tweet.
Happy palindrome day, whether you write the date DD/MM/YYYY or MM/DD/YYYY or even if you put the year first for some weird reason. 02/02/2020 is the only such date this century. The last one was over 900 years ago, on 11/11/1111. SO DON’T WASTE IT.
That would suggest (to me, a non-expert) that it isn’t based on what it knows about me. Both searches are from a regular window. Still, I’d expect a lot less variation in when it serves untested research and when it serves the consensus answer here.
Never fails. It's the posts where I don't take the time to choose my words carefully, that take off.
In the second tweet I should have said "This could mean" rather than "This means." Hopefully this is clear from subsequent posts offering other explanations.
Here’s something weird to wrap up your Sunday evening. In 1981, Dragon magazine published AD&D character stats for Bugs Bunny (15th level illusionist) and other cartoon characters.

Carl Sagan passed away
#OTD
in 1996. In his final interview he left us with two messages that are still relevant today: one emphasizing the importance of a science literate public, the other a warning about how hard it is to extract ourselves when we’ve been conned.

This is a recent proposal that lucked into a bunch of media coverage but hasn't been scrutinized yet. It drastically revises an existing result supported by a tremendous amount of evidence. That doesn't mean it's wrong, but being recent doesn't make it right.
The 6yo asked me about pianos and jazz this morning, so I played “Take Five” for her. She listened intently to the whole thing. When it was over I asked her what she thought, and she said “Did you know that teeth are a special kind of bone that can fall out of your body?”
Sister Mary Kenneth Keller was born
#OTD
in 1913. She designed Beginner’s All Purpose Symbolic Instruction Code — BASIC — with John G. Kemeny and Thomas E. Kurtz, and was the first woman in the US to earn a PhD in Computer Science.

I just finished teaching a summer course fully online, from beginning to end, and though I am still collecting my thoughts I definitely think what I liked most about the online format is how it doesn’t contribute to the spread of a virulent pandemic and potentially kill people.

I mean if lawyers are known for anything it’s spending huge amounts of their own money on their clients, with no expectation of reimbursement.
Jocelyn Bell Burnell transformed astronomy when she made the first observation of a pulsar

in 1967. She and advisor Antony Hewish initially dubbed the object LGM-1 (“Little Green Men”) for its regular signal, but soon identified it as a rotating, magnetized neutron star.

Why is the sky blue? I see a few people talking about this. You can go into lots of detail — there’s tons of physics to dive into — but let me see if I can give an explanation you haven’t heard before. I’ll sketch out an Effective Field Theory explanation of why the sky is blue.

Until it has stood up to extended scrutiny from scientists, it is not appropriate to present it on the same footing as the scientific consensus. Folks may not realize that models like this get proposed, examined, and rejected on a regular basis.
I’m a professor of physics. I don’t know any scientists who think Jordan Peterson is the serious intellectual his acolytes make him out to be. I know lots of scientists who see that he is a dangerous jerk with no real understanding of the science he carelessly misappropriates.
