The disappointment you get when Michael doesn't appear...
Royce Trofel Dotado I was expecting Michael to appear.... lol
i thought its veritasium, for that shy smile :)
XD
Hmm, Michael is on RedTube. Unless you pay, he won't be showing up.
Man, that Vsauce smartphone thing made me realize how long it's been since his last video
wow yeah
ShatterNightmare 😭
New video coming this week. On dimensions

10-yr-old Dianna was so hopeful that the metal was a meteorite. Grown-up Dianna did some calculations. A 300g piece of metal, if it didn't burn up (which it definitely would) or melt in the atmosphere would still have about 50 sticks of dynamite worth of energy when it hit the ground. Foiled!
Physics Girl OMG, we would've been extinct!!!😱😱😱
What did the metal look like?
It still could be a meteorite. It could be either what was left of a larger one that mostly burned up or a fragment of one that disintegrated. After dissipating the bulk of its kinetic energy in the upper atmosphere, a chunk of meteorite debris would fall to the ground at aerodynamic terminal velocity.
Meteorite bits are found all the time on the surface which do not appear to have hit the ground with the energy of 50 sticks of dynamite.
Could have fallen off a plane, could have been picked up by strong updrafts. Large birds like falcons and eagles sometimes grab things that look like animals and pick them up, only to realize it's not edible, and then they'll just drop them from the sky. A 1/2 pound of metal sounds about right for a large bird of prey to pick up and carry off.
Maybe your dad's truck was made of adamantium. Did your dad work for S.H.I.E.L.D. ?
When you miss your friend so you watch her videos
Making friends for that sweet, sweet watch time.
PS I MISS YOU TOO
So meet each other than... Or a skype session. Of course put the conversation on youtube ;)
Simone Giertz you could make a robot, that looks like Dianna... So you don't have to miss her... P.S. It's probably safer to just use a cardboard version ;)
come on Simone know your on some project but ... Skype call or something. ;)
You have to miss your friend to watch their video?😂😂
Smart... Phone. *CUES VSAUCE MUSIC* But what is smart? And what does it taste like? In order to figure this out, we need to understand the meaning of life.
Many people think the meaning of life is 42, but to know if that's true or not, we need to dive into the meaning of forty...and two.
Where does the word "life" even comes from ?
And what does it tastes like ?
But what is taste, what are senses. How is taste different from feeling or is taste the feeling of your tongue.
but is life real? is anything real?
STRYKA FPV
Is real really real????. Cue the mystery music
Nice Vsauce reference xD
Loved that too :)
I love that Vsause reference.
6:26 Hey, Vsauce, Physics Girl here! That really made me laugh
Haha, that Vsauce touch was hilarious. 6:23
Don't touch this it might be radioactive! *sleeps next to object for twenty years*
*YOU KILLED THAT CUPCAKE!*
SMART..PHONE*Vsuace bgm*
That coeffecient of friction mew joke is hilarious.
+Robert Joasilus gotta be a physics fan and a Pokémon fan. We are few
Physics Girl thank God for that physics class I took in college.
Robert Joasilus yep!
And mew2 is coefficient of friction doubled
Robert Joasilus I was looking for exactly this comment
Many cupcakes were harmed in the making of this video.
Looked more like one cupcake many times, unless you're counting the ones she ate.
I'm just wondering why the soup can was necessary.
I was expecting a bowling ball.
If Michael Moore had been there in person instead of just on her phone you likely would have seen many more cupcakes harmed... just saying.
😂
I wish I was half as happy about anything as you are about physics or anything you go over in these videos Keep it up girl!
I always look forward to what your next video will be, but after watching this, I am even more excited then normal for your next video!
You do amazing work!
This video needs more Spherical Electric Rodents.
No! More *coefficient of friction*
The coefficient of friction? LMAO
I was hoping someone would get that one!
whatdoyoumea
myspacearismtworkig
Considering it doesn't touch the ground, Mew must be very small ;)
I got it! And I laughed so hard at it XD
Of all the science youtubers I've seen, you bring the most energy. It's nice to see how passionate you are about it.
This channel is so nice and visibly embettering, I love it, keep up the good work!
That's one hell of a cliffhanger!!!
THE CLIFFHANGER... why Dianna
YOU STAYED!
Because that's how you keep your viewers....viewing. One day, we'll find out if that mysterious chunk of metal was, in fact, just a car muffler :P
Or a rock solid muffin?
Came looking for a comment like this lol, super keen to see it.
I believe it was a biscuit from Ellie May Clampett.
Wow, that story with your dad is so cool. You rock Dianna! Thank you for all these cool videos and content.
BTW I've just subscribed to curiositystream using your code and it all looks amazing. Thank you!
Great video, one of your best. You really stepped up your game, now that i think of it all of the pbs videos have gotten really good recently.
Upvote if you want the particle detector app!
Lisandro Pastinante I used it for about a year. Taped over my lense, ran it regularly,...ect. I wouldn't mind having it again.
What was the fastest particle you've detected?
Give us the name of the App!!
crayfis.io
3:54 I literally laughed out loud
ok
I JUST FOUND YOUR CHANNEL> AND I LOVE IT.
Such a good review and intro to new concepts for me! And it's nice to just talk about the theories and concepts and see it visually because the math part gets a little tricky for me.
I have been reading and loving Piled High and Deeper since I was in grad school 13 years ago!
Way to make Physics Girl videos even more amazing!
Hi Physics Girl, This was the best video production thus far. Loved the funny cuts and connections to other channels (ie vsauce). Good job!
Thank you! We put a lot of work into this one. I wanted it to be a bit different, with a collab, and stories and my corny jokes. Glad you liked :D
Physics Girl I digress. Your father was a great addition to the video but the jokes were mildly silly and I felt like watching Discovery channel with it's crappy content nowadays... Amusing, but useless in the end.
The video felt incomplete for a production of yours, the worst part was that there's no information about the app anywhere to be found...
Crayfis.io
So the argument is that you want to help solve this matter but end up leaving us on a bigger mistery where we don't have tools to help find clues about it?
Constructive feedback: please add information on the app in the description of the video ;)
For amusement I can go watch cat videos xD I don't want to sound rude but the jokes look immature and it's the first time I dislike one of your videos (that's alarming because when a channel starts going this way, it keeps going down).
Nice nod to Vsauce I see
Loved this episode Diana! It makes me happy to see you so comfortable in being yourself in these videos. Entertaining and engaging ☺️ Keep being you. Happy Physicsing!
Best video I've seen here in this channel, Dianna you're awesome!
Hey @Vsauce #Dianna here!
ok so this episode was so full of references oml. best physics girl video ever. also can someone explain 03:59 pls
p.s. Collab with Vsauce again pls
More = Michael Moore :P
A J ok wow I don't know him so I didn't get the reference. thank you so much tho
wooow......
this video was really quick !!!
I wasn't at all expecting a PhyGi video right now...
Coming to the video, your videos getting exponentially great Diana!!!!! love your work...
(sorry for long comments- too excited!)
Diana you're awesone. Keep making physics fun!
The Vsauce soundclip made me spit my beer XDDDDDDD
Dammit, now I want to go hunt particle mysteries. And I'm hungry. And I want to watch Vsauce. Great video! ^^
Great video and content and I thoroughly enjoy your lively presentation. I envision your channel reaching children and teens the world over and motivating them to love science as you do. Thank you for what you do.
I love your sense humor and your smart brains. :) Love your channel! Thanks
vsauce parody moment was super funny :)
I know I'll never be borred with that girl!
WOW! This was a REALLY GREAT video! Well done!
This was so awesome. Well done.
Hey physics girl! #NotificationSquad
HUZZAH!
Physics Girl could they be from the big bang? 😮
Coefficient of Friction... Mew... Mu...
Punny.
Donald Sleightholme No. No particles existed at the Big Bang. Several hundreds of thousands of years passed before the universe cooled enough for particles to exist for more than a few seconds.
Yeah!
I thought you were making d.o.n.g 6:25
Love your videos, keep it up!!
I can't express how much I love you. And also, how IMPORTANT people like you are to our numbed society. Never stop making these videos. I am going to lobby the NEA to make your channel part of the science curriculum in this country. I mean... if we still have schools in a few years.
Dianna, you can't just cut off the video like that.
SAY HI TO MEE ... !!!!!!
heyyyyy.
Arun Kumar hi
OMG I CAN'T BELIVE THIS!!!!!!
Arun Kumar SLOW....... CLAP 👏........👏..........👏
Hi
It all makes sense now, this video was posted the day I had my 8th grade math exam. Even if at that time I had any idea what UA-cam is, the existance of this video and 10-year-old Dianna's presence sent me energy and took that exam with 100/100. Thank you, Dianna! 😀
Awesome videos, I like them so much. A big shout out from Argentina!
Yay! Great surprise at the end 😃
Absolutely adore Diana's enthusiasm!!! Whenever I'm feeling blue, Diana is always awesome for a laugh!!!
I just need to take a moment to express how much I f#$king LOVE this channel! Thank you so much for taking the time to share this amazing and complex information with us in a way we can understand! So great : D
Hey Diana, your videos are really good 😱😱
Dianna is a wonderful physics professor in an approachable human form. I wish I had such teachers in my schools! Thank you for all the young people you are affecting with positive energy - cosmic?
I just realized with this video that I love you
I love the quirkiness of this channel!
you were on point in this video. loved it! X'D
We all love your videos ❤
I love the PhD comics!!!
I love the way you explaining things.
And how cute you are while eating things! 😊
I use a technique called Raman Spectroscopy to determine molecular composition of plastic, and occasionally we get huge peaks, higher than anything else, and I was surprised to find that they were called cosmic spikes and actually originated from cosmic rays.I thought that was so cool!
And as always.... a great video.
Love your videos Dianna.
One of the funniest Video i see coming from your chain
I feel like your free yourself more and more to show us who you really are (a funny and Physics .... girl :D )
Just keep doing what you do :p
You are so funny and entertaining while being informative.
Brilliant and fun video. Thanks!
I'm looking forward to part II where we will see the mystery object.
You are so wonderful! Makes Science so fun!
Love your videos!
"It was in his nightstand."
Oh man, that's going to be me when my kids are our age.
Excellent video my dear Diana! I wonder if this cosmic rays where the same rays Tesla wanted to use as a giant source of positive charge...
I always enjoy your uploads, but the VSauce bit made me smile. Thank you.
What a great dad! (Aside from swiping your mystery metal.) It sounds like he really encouraged your interest in science.
Ha ha, this was way funnier than any previous videos of yours I've watched. Thanks, and stay in this groove!
Awesome channel you kick butts.
that is awesome, thank you! i want that app...
We need to see it!
LOL!! I am subscribed and love the Vsauce ref. I'll keep watching for more ......... and meteorites.
thanks Michael, i mean Dianna. love your work! 💓
Cool episode!
How would you use a smartphone to detect cosmic rays?
Died at the cupcake part 😭😂😭😂 "nobody knows"
6:27 just made me fall out of my chair!
I think more youtubers need to make more reference jokes (:
Well played Dianna!
amazing video!
you are awesome, it was really funny n interesting. you are really good teacher with fun. thank u.
Could you please do one on the new gravitational wave discoveries?!
Oh you do your videos so well! coooool...and funny! :)
This is so sweet. I love it. Disclaimer: As a kid I collected all kinds of rocks. Some of them actually meteorites. Some turned out to be fossils. SCIENCE!
I.... I..... I think I love you Physics Girl! That video was hilarious 🤣🤣🤣
I would totally run that app on my phone. I'm running BOINC screensavers on both my laptop and my desktop right now.
this vid is golden! ✨💫☄️
Your sense of humor... thanks!
Possible answer to the question of where do the super high energy particles come from: "astrophysical shock acceleration", or stochastic scattering back and forth across an astrophysical shock wave (such as from a supernova explosion). It's a reference frame thing, combined with statistics. Each time a particle is scattered upstream and then back downstream across a shock front, it picks up an increment of velocity/energy related to the difference in temperature between the heated (shocked) side and the ambient (unshocked) side. Rare particles scatter back and forth very many times and build up incredible energies. My master's thesis was a Monte Carlo simulation of astrophysical shock acceleration aimed at explaining the power-law spectrum of the high energy tail of the cosmic ray energy distribution, back in the 1980s. Somebody probably knows a lot more about this nowadays. Thanks for the blast from the past!
*Would you do Q and A videos?*
What about that trick where you put a small ball on top of a large ball and drop them both. When they hit the ground, all the energy from the big ball is transferred to the small ball causing it to go flying off at a non-intuitive speed. Would that energy transfer concept work with particles?
You get a gaussian distribution of energies from just about any source . These high energy particles are clearly at the high end which is why they are so rare. I suspect particles bumped up in energy near black holes. You get a log jam of sorts, everything can't make it into the hole faster than what's coming in behind so some of the stuff gets pushed up to high enough energy to escape and a few that get really bumbed up. Since the stuff is already orbiting near light speed near the event horizon that's quite a potent engine.
Lovely episode... and I loved the puns!
She pulled off a VSAUCEEEEE! You're great Dianna.
I love that φ is your brand symbol. Very cool
