To further accompany problem identification (than already done in the interview), here's a video of Gary Stevenson's about #solutions and #opportunity (to win the ideological theoretical debate) with the #povertymajority, big #demand for alternative, in #awareness of the #statusquo not working, and about helping people understand what's happening and build on that understanding ( #educateyourselfsoyoumayeducateothers ), reform, democratic pressure, ... not hopium to placate you back to defeated slumber.

... and while I'm at it, here's the explosive first interview from a year or so ago: https://www.youtube.com/watch?v=ViY-zI3b5JQ


There are so many many portions I could have quoted from that interview. Hard to pick. Here's just a couple.

"a call to arms."

"... [the book is] a massive opportunity for me to spread awareness of these problems"

"...this beautiful and horrible irony that if you can convince poor and ordinary people to be very very selfish in a material sense, you will completely materially impoverish them."
"So this is this amazing irony that if you cam make poor people obsessed with getting rich, they'll become poor."

"It's kind of a moral test for our society: are you willing to put your selfishness aside enough to protect your selfish interests?"

"The rich have got so much money now, they have to do something with it, they can't just sit on it."

interviewer: "I think I saw a statistic ~ this is from 2019, it's probably worse now ~ one in six baby boomers is a millionaire. Right? That is... ~ if you want to talk about the people who do the door knocking for the conservative party, that y'know... they will vote in every single bloody election for the Tories and think the sun shines out of Jeremy Hunt's backside, even when they're as terrible as they are right now. You look at the polls, and who are these 25% of people? It's those people, and the people sort of immediately around them."

A few weeks ago, I posted an example of a #projectile #trajectory in a uniform #GravitationalField without #AirResistance. It's a school-level exercise but it was nice to produce an #animation for it. To model air resistance is a bit more tricky as any #fluid, including #air, is complex and does not necessarily behave as you might expect. A simple model for it might be to assume it is a #linear #viscous fluid offering resistance proportional to the velocity of the projectile, i.e. R = -k.v, where v is the velocity vector and k is a constant which dictates how viscous the fluid is.

Happily, this model has exact solutions so I didn't need to do any numerical integration to find the form of the displacement. Here are four different cases, including the "ideal" case k = 0. The others are k = 0.1, 1 and 10, with the middle one highlighted. The essential difference between the non-resistance case and the others is that horizontal velocity steadily decreases with time and decays towards zero exponentially. The vertical velocity is also reduced but still grows. The most viscous case (k = 10) shows terminal velocity behaviour very quickly and the projectile appears to be moving through treacle.

Dashcam Detective Work Leads to Recovery of Space Rocks from Fireball over Slovenia

On 28 February 2020, at 10:30 CET, hundreds of people across Slovenia, Croatia, Italy, Austria and Hungary observed a bright ball of light hurtling across the morning sky. This delivery of rocks from a distant asteroid to the fields and villages of southern Slovenia was captured by cars’ dashcams, security cameras, and even a cyclist’s helmet. It is one of only around 40 fallen space rocks that has been recovered within weeks and for which the origins in the Solar System have been tracked.
