Laser Expert Explains One Concept in 5 Levels of Difficulty | WIRED
Donna Strickland, PhD, winner of the 2018 Nobel Prize in Physics and a professor at the University of Waterloo, is challenged to explain lasers to 5 different people; a child, a teen, a college student, a grad student, and an expert. Also, check out the free WIRED channel on Roku, Apple TV, Amazon Fire TV,…

Are we just going to ignore the laser “expert” shined a flashlight in a 9 year old’s eyes?

Lol she is terrible at teaching but I can see her passion for her subject. Will probably do way better in research.

What I like about this series is that an average viewer can somehow jive with conversations between two experts by spoon feeding simpler explanations first

I’m not certain, but I think she went deeper with the 12 year old than she expected to.

I’ve always found that this kind of tailored communication – the ones ive seen who are the best at it… are all women. Maybe they’re uniquely good at reading reactions ?

Seems to me that to understand lasers one ought to understand the nature of light. Light is just so mundane and abstract at the same time.

Can I use lasers to pump chloroplasts and keep photosynthesis going? Coupling this to a CO2 meter could make this process ridiculous efficient. Could this be a thing or am I just daydreaming?

My bachelor’s is in photonic science and engineering, the expert level in this video isn’t even speaking at the master’s level in photonics. Try sitting though a non-linear optics or quantum optics lecture at the graduate level. It’s crazy, I feel so stupid compared to some of my old professors.

She is smarter than anyone i know and will ever know, and she knows more on the topic than anyone else. But its pretty clear that she isn’t a good teacher.

laser is to light what a whistle is to sound.
Charlie Angkor
November 8, 2019 at 1:33 pm
if you shine light into a darkened glass, it diminishes in brightness with distance. in a laser there is an opposite stuff. You shine weak light in and its brightness rises as it travels through and comes out brighter. Then someone came with an idea to put two mirrors around it so it builds up its brightness to infinity.

I designed a DIY “laser” wireless optical datalink 1.4 km 10Mbps full duplex. Except it doesnt have a laser, but an LED. Lasers are bad for this. Eye safety, expensive, complicated to drive, easy to destroy, coherence causes black spots wandering over the receiver and causing signal dropouts. Requires expensive sharp optics.
Charlie Angkor
November 8, 2019 at 1:40 pm
with her laser hammer she probably blows a lens or a mirror or fries a fiber before it even comes out of the laser 😂😂😂
Charlie Angkor
November 8, 2019 at 1:41 pm
I shone a 5mW laser pointer into an optical fibre and it smoked and melted and stopped working because the carrier plastic was black😂😂😂 now imagine your retina smoking and melting.

so if I put her terawatt or what laser hammer into my Ronja how many kilometers of dense fog will it punch through? 😂😂😂 will it be eye safe? 😂😂😂
