How fortunate we all are to have such a distinguished and brilliant physicist describes very fundamental connects in physics. I love Lawrence Krauss for his deep knowledge, for being so generous of his time and for his appreciation of physical universe phenomena. Not to mention his wits. I think Dr Krauss is one of the most spiritual persons without believing in man-created gods

[@lkrauss1]

thanks!

[@shaolin89]

Just make all of the episodes +10 minutes. Preferably 20+! Thank you for this wonderful content, professor!

[@user-sl5nm9js8p]

You just blew my mind Lawrence... Again. And I love it :)!

[@johnelliott1846]

Thanks for doing this Professor Krauss. It's very kind.

[@thejbcrazy]

Wow ... Kewl ... thanks for sharing ...

[@naturediary7651]

Another great video Lawrence, so interesting. Thank you.

[@MrMikeWyn]

Very nice lecture. Thank you, Dr. Lawrence Krauss.

[@dpwright32]

Lawrence, I've watched literally thousands of videos on this kind of stuff, and never ever understood what you just explained. So many lightbulbs just went off in my head. Thanks again.

[@ShadowZZZ]

One reason I love some of the equations in quantum mechanics is because they combine lots of physical constants, including: c, h, π, ε, m, q

[@yosirking]

Well I need to watch that again. Keep them coming please

[@zahariachirica5466]

Great professor!

[@udaikumar1782]

Thanks professor for the wonderful content. Respect !!!!

[@woody7652]

Over ten minutes is more than twice as good.

[@jacobbond9796]

I like the feeling when I see/understand something for the very first time and it's big. And you deliver such a moment with every of these videos! Now knowing that you can relate mass, energy, time and distance it feels like a new view on the entire universe opend up in my head. Thank you!

[@stavrosmaiden]

This was my favourite 5 mins video so far!! I obviously knew about the Heisenberg principal (I am a materials scientist with a PhD in Materials Engineering) but I did not know how physicists applied it to understand new particles or new interactions between particles. Thank you Lawrence you are amazing! Since I found out about you I've learned so many different things about our universe!!

[@lkrauss1]

thanks.. that makes me feel great! hope you keep enjoying them.

[@stavrosmaiden]

@@lkrauss1 I am sure I will!!

[@ByronMarrMusic]

Love it, you explain complex stuff in such an understandable way

[@DaxLLM]

Thanks! That was good..

[@shellderp]

this is absolutely fascinating

[@AliIShaki]

Thanks. Very clear and mind blowing at the same time.

[@matiastrujillo1995]

Greetings from Argentina! Love your lectures!

[@rbenchraa]

This was mind blowing, thank you

[@domcasmurro2417]

He is really good at explaining these subjects.

[@wilsonseto1]

man, these videos are good. One day, inadequate professors will show your videos in class!

[@mymomentsofzen6005]

I am starting to get it!! The part that I am missing is the basic vocabulary. The symbols that physicists use, and the knowledge of those symbols is where I am lacking. I guess that gives me another thing to search for while I have this time. I was always afraid of math, as I was taught math in a time when it was not explained as what it really is. The language of reality. My son was taught that way and he now designs jet engines for a living!! But even though I don't always understand everything that you are teaching us, I am absorbing all of it! Keep it up. These are fascinating mini lectures!

[@thiagarajang6813]

Excellent

[@kaybei9771]

Prof. Krauss can you recommend a textbook which shows how you can derive interesting equations using dimensional analysis like you mentioned at 2:20.

[@Saitama62181]

Mind blown.

[@D.C.]

Please add all these videos to a channel playlist called "5 Minutes Physics" so we can play them all in series. Thank you for doing what you do! Big fan!

[@lkrauss1]

ok.. they are all together on the Lawrence Krauss channel so you can watch them that way.. but will create a playlist.

Good five minute video!

[@flyonbyya]

The longer the video...the better

[@Seekthetruth3000]

One of these days, I'm going for that PhD in physics.

[@experienceanimation217]

Seeee when it's explained in plain English it makes sense

[@TenEighty1080]

Excellent video, thank you! Are you referring to the discovery of the J/psi particle by Ting & Richter in 1974?

[@lkrauss1]

yes

[@mfpaint-j5s]

"All this became relevant in 1974 when two groups of experimentalists were banging..."

[@TheD4VR0S]

Apparently the electron has no known size can we use it's energy to measure it's size ?

[@markmd9]

The group he was talking about was the one that discovered the Higs boson? Or he was meaning other particle?

[@lkrauss1]

another one

[@rhythmpants]

I'm in way over my head here, but I have a question. Why does entropy not play a part in Plank's constant?

[@lkrauss1]

in a way it does.. entropy is actually related to number of photons, but number of photons depends on planck's constant..

next one will be.. I promise.

Don't want to die stupid but this is like fighting the wind

[@ezsparky]

Dr. Krauss, could you do a video explaining the physics on how 5G does not or cannot cause damage to the body because the radio frequencies used in 5G are not ionizing radiation? I have been trying to explain this to friends and it would help to have an actual physicist explain this where we could direct them to you in a video explaining this issue. Thanks!

[@lkrauss1]

maybe.. I may talk about relative energies, etc..

[@ezsparky]

[@randomthoughts9820]

It's a pity that such a brilliant physicist had to become a victim of cancel culture. Glad to see him back as a public educator par excellence.

[@LeventPostoglu]

Hi Lawrence, I thing we don't explain the energy very well, do we? We don't know exact meaning of energy? What is the real meaning of energy? Can you explain in a 5 minutes Physics? How can energy change to matter after 300 k years after Big Bang?

[@lkrauss1]

hmm.. will think on whether I can add anything useful to that in 5 min

[@LeventPostoglu]

@@lkrauss1 Ok. Thanks. You are great. :)

[@BBStub3]

I Love you so much but you have a fetish for Nobel Prizes :))

[@Petrov3434]

Uncertainty (principle) -- Heisenberg named in German with perhaps a more appropriate term -- "un-sharpness" (principle) Hence it is perhaps like a "smudge" -- like in various forms of summing of sinusoidal waves -- an illustration of how the flexibility of German language makes it nearly ideal for science (despite very long word construction)
