Gravity visualized with a big sheet of stretched “spandex”…

Basically the same thing.


#3

To the barn FOR the pole shrinks and the barn doors can be closed for an instant with the ole completely inside

Something sentence with rong.



#4

Must be nice to have a high school science budget like that.


#5

If a person is running at 0.87c though a barn?

Like so:

yep, heart of silicon valley; property tax revenues thru the roof (so to speak). meanwhile just 40 miles away in oakland…

Colbert Show had a fun demonstration using this technique:


#8

To the reader FOR the sentence shrinks and reader eyes can be closed with the ole completely inside.

See?


#9

Isn’t it a fail when videos about relativity have non-relativistic timestamps?


#10

FOR = frame of reference


#11

barn doors can be closed for an instant with the ole completely inside

olé? I’m suddenly envisioning the barn contorting itself out of the way of the pole, like a bullfighter. It’s the cartoon universe resolution to the problem.

Great to see that level of enthusiasm, and joy for a subject,coupled with teaching other people his best lessons and showing them how to make relativity come alive in the classroom.

He also mentioned “It’s not on the test, but let’s do it anyway”. A sentiment that’s all too rare because so many school systems discourage it entirely.

And on the “paradox”, this seems apt:


#13

Why is there a guy with a boner at 7:00? Too close to the latex?


#14

the barn doors can be closed frame of reference an instant

???


#15

ELIZA, is that you? :wink:


#16

What makes you believe this is me?


#17

Can you elaborate on that? :expressionless:


#18

Kind of pitiful that $100 (his quote) really probably is more than most will spend.


#19

Zentai Gravity?


#20

The barn gets shifted into a parallel universe where scientists have to live in monasteries.
