Yup. The one-and-only @lindseyvonn  asked me about astrology. I gave her a succinct answer. #AthletesAskNeil  @PlayingwScience  @uninterrupted  [Video: 40 sec]

@levarburton  The recurring phrase, now excised from most modern cuts of old films was “Free White and 21”. A boast that the person was “Beholden to no one”. An offensive script line that was nonetheless true and accurate. Here’s a compilation:

@stevendotmalone  No vectors in E=mc2. Energy has no direction. Neither does the square of a velocity. But momentum does. So P = mv is a vector. With P and v in the same direction, as written.

I dream of a world where truth shapes people's politics, rather politics shaping what people think is true.

@jjon47470311  @elonmuskN  @mccadesmitho  @BillNyet  especially hard. The number on the right is first the difference, then sum, of the numbers on the left. But in any case, I often wish Mensa people would spend more time solving world problems than puzzle problems.

A picture is worth a thousand words, except for pictures of words that contain between 1 & 999 words.

Agreed. It doesn’t work for textured meanings within sentences.

Good Luck to @elonmusk  and the @SpaceX  crew. Though it’s rocket science, rocket launches can still use a little bit of luck.


His passing has left an intellectual vacuum in his wake. But it's not empty. Think of it as a kind of vacuum energy permeating the fabric of spacetime that defies measure. Stephen Hawking, RIP 1942-2018.

SCIENTISTS: “We’ve produced the first-ever image of a supermassive Black Hole, 55-million light years away” RESPONSE: “Oooh!” SCIENTISTS: “We’ve concluded that humans are catastrophically warming Earth” RESPONSE: “That conflicts with what I want to be true, so it must be false”

Evidence collected over many years, obtained from many locations, indicates that the power of Prayer is insufficient to stop bullets from killing school children.

In the past 48hrs, the USA horrifically lost 34 people to mass shootings. On average, across any 48hrs, we also lose… 500 to Medical errors 300 to the Flu 250 to Suicide 200 to Car Accidents 40 to Homicide via Handgun Often our emotions respond more to spectacle than to data.

In school, students cheat because the system values high grades more than students value learning.

Look what happened the last time you didn’t vote.

You know it's true… Every disaster movie begins with a scientist being ignored.

You Matter. Unless you multiply yourself by the speed of light squared. Then you Energy.

I dream of a world where the truth is what shapes people's politics, rather than politics shaping what people think is true.
