Fantastic video Dr. Sutter! You have a real talent to teach and tell the whole story, so to speak. Very engaging and look forward to catching up on all of your videos. Thank you for taking thr time to develop this fantastic content!
Please do a video on Delayed Choice Quantum Erasers: A delayed-choice quantum eraserexperiment, first performed by Yoon-Ho Kim, R. Yu, S. P. Kulik, Y. H. Shih and Marlan O. Scully,[1] and reported in early 1999, is an elaboration on the quantum eraser experiment that incorporates concepts considered in Wheeler's delayed-choice experiment. The experiment was designed to investigate peculiar consequences of the well-known double-slit experiment in quantum mechanics, as well as the consequences of quantum entanglement. The delayed-choice quantum eraser experiment investigates a paradox. If a photon manifests itself as though it had come by a single path to the detector, then "common sense" (which Wheeler and others challenge) says that it must have entered the double-slit device as a particle. If a photon manifests itself as though it had come by two indistinguishable paths, then it must have entered the double-slit device as a wave. If the experimental apparatus is changed while the photon is in mid‑flight, then the photon should reverse its original "decision" as to whether to be a wave or a particle. Wheeler pointed out that when these assumptions are applied to a device of interstellar dimensions, a last-minute decision made on Earth on how to observe a photon could alter a decision made millions or even billions of years ago. While delayed-choice experiments have confirmed the seeming ability of measurements made on photons in the present to alter events occurring in the past, this requires a non-standard view of quantum mechanics. ..[clarification needed][2][3]
Paul, love the historical aspect of the presentations. Really holds my interest. Are you going to continue right up to the discovery of quarks and how that happened?
Hey Dr. Sutter, I just wanted to point out a small error you make around 5:11 into the video. You say "Johnson, JJ Johnson" (a jazz musician, according to the quick google search I just did), and I believe you meant JJ Thompson, the Nobel laureate physicist. Thanks for the video, love your content.
Admiral Rickover would say: The only persons that can say 'we' are sovereign heads of state, pregnant women, and schizophrenics. Which one are you? Just thought you should know.
Time travel into the future is certainly possibly, we're literally doing it right now :) Time travel into the past appears to be forbidden, but we don't fully understand why.
I've had both cats and kittens in boxes many times, all of them have lived, have I encountered immortal felines? or am I conducting the experiment wrong? Sometimes they'll appear in boxes without assistance but only after making an observation? Yet the other half or the time I find the boxes are empty? Occasionally I'll even see similar unfamiliar felines way outside the parameters of the test, sometimes even under vehicles or out in the vacuous expanse of my lawn popping in and out of existence when checking every few hours? 🐈+🔲=?
I really enjoy the episodes where you delve into a bit of the history like this.

Very good!
So much of this I've studied for radiology, or very closely related.
It's so easy to forget this stuff! Love your work and presentation.
Awesome, thank you!

You got it, it's on the list!
I like these "how did we discover" videos. Keep up the good work Paul.
Thanks, they're really fun to do!

Love these videos on the history of science!
Thanks, they're really fun to do!
Great vid as always. Thanks.
Thank you, I appreciate it!
'By the 18 th century, we" Wow, Doc, you don't look a day over the 20th century : )
I lost my hair in nineteen dickety two but other than that it's been a great run.

Just thought you should know.
This was great cant wait for part 2 hahahah!!!! im from Nz Ernest is my hero!!!
he is also on our $100 dollar bill !!! legend
All the Ernests of the world please stand up!
5:10
I suppose Mr. Thompson wouldn't like being called JJ Johnson
You're like a mad chilled physics evangelist!
Thank you!
Hi Paul. would you agree with statements that says in quantum mechanics time travel is physically possible.
Time travel into the future is certainly possibly, we're literally doing it right now :)
Time travel into the past appears to be forbidden, but we don't fully understand why.
@@thecaptain2281 no, but that dosn't mean I don't believe that you believe

You might want to take a break from....well, just a break.
Lightbending screen 😀
Indeed :)
Do we have any idea of the size of the unobservable Universe? (No mom jokes please)
