She addresses this in a follow-up video (still doesn't have the real experiment, but does have Neil deGrasse Tyson):

Was hoping for an actual experiment.

You cannot both "detect" a photon/electron before it "enters a slit" and have it go through and "detect" it again at the back. That part is (probably) hogwash.

Detection at this scale really means fatal crash or at least deflection.

From what has been observed it would appear that in such an experiment an individual electron takes all the possible paths through both slits and the "waves" that "interfere" are waves of probability of the particle passing through detection points.

While it might as well be magic, really, QED does have observable rules, and this video might make it appear as though one could change the outcome by blinking an eye, which is not the case.

To make any headway stop thinking about tiny marbles. Think about tiny cartoon characters moving so fast they are smudged to invisibility whirring their tiny appendages around - you can only tell which particle and where it is if you swat it or it hits a wall and stops moving. There is no "detect but keep going as if nothing happened".

That is how you fix it if you are using the old sift format. In the new sift you scroll over your name in the top header and a drop down menu with an "edit this video" button, will appear.

If you want to fix it, look for the words "edit this video" underneath the video, bottom left.

Ah! Excuse me for being vague.

Girl is a young person. Age 17 or less.

A woman is a world class athlete.

If you want to fix it, look for the words "edit this video" underneath the video, bottom left.

Click on that and you can fix your description. If you want to.

Please excuse my English, how? Is it just the apostrophe? Apostrophes on a Czech keyboard are a pain. Also, I humbly admit, I have no idea how to edit that text now :-(

And she definitely let the other girl go, also I am not aware of any tradition of this happening regularly in biathlon or cross-country skiing when sticks break or are lost due to contact.

Happy anniversary! Today marks year number 7 since you first became a Sifter and the community is better for having you. Thanks for your contributions!

If you're interested, my thought is badly prepared because I got the impression she had just received the information. At any rate ... the planet is a giant shitshow all around and I keep hoping to wake up from a horrific nightmare. Far worse than I could ever have fathomed. I know ... call me buttercup snowflake. Thanks for being you vil

But the first 9 minutes is either badly prepared or badly executed IMHO. The first minute is pure WTF bad.
