Many of these may be accurate, but I think several (like #1) are based on the idea that you have Facebook on your phone, and use it all the time. I don't have Facebook on my phone (or any social media app) and use it on a desktop, only several times a day.

I've read most of his puzzle and math books. Like Asimov, he mostly wrote non-fiction and dabbled in fiction on the side (though of course Asimov's works number in the hundreds).

Picturing Math: Selections from the Department of Drawings and Prints| Metropolitan Museum of Art| Exhibition
"In 2015, the Metropolitan Museum of Art acquired a series of prints of the most beautiful equations, as drawn by 10 prominent mathematicians and scientists. Mathematician Stephen Smale, for example, chose the relatively simplified numerical analysis equation known as Newton’s Method, first published in the 17th century, while theoretical physicist Steven Weinberg’s demonstration of the Lagrangian of the Electroweak Theory, which contributed to his 1979 Nobel Prize, flows over four dense lines. The 10 prints of mathematical expressions known as the Concinnitas portfolio are the core of Picturing Math: Selections from the Department of Drawings and Prints, currently on view in the Met’s Robert Wood Johnson, Jr. Gallery."

I've been sorting out my external backup drives today. They've been "standardized so that I have a similar folder structure on each. Really important if I ever want to find anything to restore. Just as well as I discovered just over a 1/4 of a terrabyte to backup!
However, this all takes MUCH LONGER to do than hoped. Oh well. I can always walk away and come back to it later.

One bit computing, with NO electronics!
One bit computing, with NO electronics!
Originally shared by Ed S
A DIY paper computer, from 1958... just add scissors and pins and an hour of your time. But don't get over-excited, this is just 1 bit computing, unlike the much more sophisticated 3 bit Digi-Comp I from 1963. What does a 1 bit computer do? Depends on the instruction length, of course, but in this case it's a zero bit instruction - it can only do one thing, which is to accumulate from one storage register to the next. I'm not entirely sure, but I think that means it can toggle one of two bits. Nonetheless "the computer expert will recognise that [this machine] contains most of the units of a large-scale computer, but in simplified form."

A spiral galaxy is a class of galaxy originally described by Edwin Hubble in his 1936 work The Realm of the Nebulae and, as such, forms part of the Hubble sequence. Most spiral galaxies consist of a flat, rotating disk containing stars, gas and dust, and a central concentration of stars known as the bulge. These are often surrounded by a much fainter halo of stars, many of which reside in globular clusters. About 77% of the observed galaxies in the universe are spiral galaxies. Our own galaxy, the Milky Way, is a typical spiral galaxy.

At the centre of the controversy is a popular theory that our universe inflated like a balloon right after the Big Bang. One group of scientists essentially said this theory wasn't science — which is like calling artist's work "not art", or a chef's "not food".
Except that Science is not like Art or Food. The definition(s) of art change over time, and what might be food to some might not be to others (says someone who's lactose intolerant). Rather, if it's science it can be tested.
If it's science (see http://undsci.berkeley.edu/article/whatisscience_05) you can devise a test in which, if the theory is correct, you can make predictions by using that theory which will either be confirmed or proven incorrect. If you can't do that, it's belief, not science.
