How to lie with data
A comprehensive guide

Finally finished a small guide on -how to lie with data- ! Take a look:

Or, in other words, how to protect ourselves from the chaos of information out there... 🧪🔭📈

LISA moves forward! 〰️
Today, at the #ParisAirShow, ESA and OHB System AG have sealed their agreement to build ESA's Laser Interferometer Space Antenna.
The triple-spacecraft mission will be the first space-based observatory to study gravitational waves 👉 www.esa.int/Science_Expl...

Money and murder: the dark side of the Asilomar meeting on recombinant DNA
The famed 1975 conference about a controversial genetic technology is feted as an example of how scientific self-regulation works. But more significant is what wasn’t discussed.

They found a way to litter from space
Something else to thank EM for.
"The sustained rate of daily reentries is unprecedented," says Jonathan McDowell, an astronomer at the Harvard Center for Astrophysics who tracks satellites. "They are retiring and incinerating about 4 or 5 Starlinks every day."

A very fascinating paper went up on the arXiv today!
Jesse Han & El-Badry et al. reanalysed the 21 known 'hypervelocity' stars in the #milkyway.
They find strong evidence that the LMC (Large Milky/Magellanic Cloud) has a supermassive black hole at its core! 🤯 arxiv.org/abs/2502.00102

My favorite serendipitous alignment of paper topic and author names occurred #OTD in 1992, when Dr. D'Eath and Dr. Payne submitted 3 papers to Physical Review exploring the physics of black holes smashing into each other at relativistic speeds.

I think some people hear “grants” and think that without them, scientists and government workers just have less stuff to play with at work. But grants fund salaries for students, academics, researchers, and people who work in all areas of public service.

I've always disliked the view that the value of a degree is in landing a job
Education is for life. A job is a small (but important) part of life
I would love to teach because you find the topic fascinating, rather than because your employer doesn't want to train you themselves

Today I was asked in an interview about folks who use the weirdness of ✨quantum✨ to hawk pseudoscience junk. I think that kind of grift proliferates because of a big misunderstanding a lot of folks have about quantum mechanics, which is not really their fault!

OK- here we go. Sorry for the delay, I was not prepared for the exertion required in the thrill-a-minute adventure that is… CACAO FERMENTATION.
Yes, this will actually take 5 days. After that two days of drying. I’m not making this up. Nothing happens. Really. You’ll see.
Anyway, off we go!

"cold, desolate, empty space" is a great name for a band 🔥
Greetings new followers! Keep in mind that most stars that will ever be born already have been; the last red dwarf will exhaust its fuel in 10^15 years; and the last black hole will evaporate in 10^100 years. After that, nothing but cold, desolate, empty space, for all eternity.

The "Arecibo Message" was beamed towards globular cluster M13, in the constellation Hercules, #OTD in 1974. The broadcast took place during the dedication of an upgrade to the radio telescope.
It was the first message sent with the intention of alerting extraterrestrials to life on Earth. 🧪 🔭 👽
