TheZarcFiles Hey pal. First and foremost, just know that Uni is a great place to be. You won’t know it at first, but the people you meet and the things you do will be the best things you’ll experience! As for why I took on Chemistry, the short answer is that I love it and it’s the course where pieces fit together perfectly in my head. I only realised this in my last year of College. Finally, I look to get a PhD first, then move onto working at Google. I know it sound weird, but a lot of people don’t understand how Chemistry can branch into Finance, Tech and the rest of the Sciences due to the problem solving skills you gain. (Google because I’m a bit of a tech geek myself😊). Hope that answers your questions, and I wish you luck on your Journey👍
Kamari Weaver I currently study multiple classes. This semester I’m doing: Organic, Computational, Quantum, Spectroscopic, Physical, Inorganic and Matter States. It’s a lot😅
You flew right past it, but a video on the reflectivity of metals, the dulling of it by oxidation, and how mirrors protect the reflective metal with glass and its relevant quantum properties would be amazing.
Love the video, do please maintain the especific topics, even though I really like the maps, the specific topics dealve much deeper in the subject and are therefore really interesting
All you had to say was “light behind the gas” and everything clicked. I wish my professors could clarify small details like this, it makes it so much easier to understand
Fascinating video! I was recently listening Human Universe in which he discusses the possibility of aliens in our galaxy. So I wanted to learn more and came to this video and I loved this explanation of Atomic Spectroscopy.
Fabulous, my friend and i are artists and we're collaborating on some spectroscopy inspired work, she's going to love this video! great stuff as always
Thank you so much. Seriously this is so helpful. I'm in AP Chemistry but I'm taking it online and they just threw us into an assignment without teaching much of this
For 80 years we have tried unsuccessfully to determine if life ever existed on Mars. If we can't confirm whether or not life exists or ever existed on a planet in our own solar system, don't expect any definitive answers regarding life existing outside of our solar system.
Well, Mars has barely any atmosphere to begin with, also he was talking about having enough bacteria or higher life forms on the planet to actually make a difference in a 'usual' atmospheric composition. So this scientific method not showing any results on mar5s means there is no copious amount of lifeforms, but doesn't mean there isn't any at all. :)
It's annoying when religious people say that science is just a collection of assumptions and is solely based on guesses and its just a western ideology. While it's actually the hours of tedious work done by intellectuals to find and know the truths of the knowable universe. keep it up this video is amazing .
I probably won’t miss your Channel ….. I already have love this channel It is great for learning English and I really crush on science . What I just found 💓💓🍀
Thank you for the video. Please, explain every method in a separate video, because these were only a brief introduction or only a definition of each method or concept.
THE BEST - Your every video is great, I mean, how can one know this all? Like, you know everything about science. | Are you only one making these videos or a team?
Please do a video to explain just how much about a distant solar system we can know just by atomic spectra and transits Say the temperature and hence luminosity of the star, how far away it is, metallicity etc.
Why does a solid emit a continuous spectrum and a gas only a discrete one? I mean, if the thermal radiation comes from accelerating and decelerating charges due to thermal motion (right?), and the thermal velocities spectrum in a gas is continuous (maxwell-boltzman distribution), shouldn't the radiation spectrum emited also be continuous?
Yeah interesting question. I'm just thinking this through: light (electromagnetic radiation) comes from the oscillation of electrons. Oscillation is the important concept here. So yeah, in a hot solid you have atoms with electrons attached vibrating in a large distribution of vibrational modes leading to the thermal spectrum. In a hot gas, the thermal velocities do follow the Maxwell-Boltzmann distribution, but you don't get the continual oscillations. For a gas particle their interaction times are very short compared to their free flying time. I guess you would get short pulses of EM radiation each time you get a collision of gas particles but the energy of this is so much lower than the source spectral lines (which come from an entirely different process to oscillations) that it probably looks like a noise background. So yeah I think your intuition is right. I wonder if anyone has measured this?
@@domainofscience Thanks! You are talking about Bremsstrahlung, and yes, is much weaker than the light emitted due to deexcitation of electrons. Let's supose we have a gas at 3700 K. Then, it's black body curve peaks at red, and a red photon has around 2 eV. On the other hand, if you compute kT at that temperature, you get less than 0.5 eV. So even if you stopped the particle completely it wouldn't have enough energy to emit that red photon. Particles accelerating due to collitions don't seem enough to explain a thermal spectrum... so why does the sun exhibit one? It's gas and plasma, it cannon have any colective vibrational modes like in a solid. Where does this "extra energy" come from to explain a thermal spectrum? I haven't found a satisfactory answer to this, and I've been looking for months. I don't really understant where does thermal radiation come from. I would like to discuss with you some topics about thermal radiation and rayleigh scattering (for example, the role that resonant frequencies in the atmospheric molecules play in the fact that blue is more scattered than red, rather than particle size compared to the wavelenght of incident light). If you are interested, we can exchange ideas! email me: sergitorres17@gmail.com And thanks for replying, apreciate it.
This is by a large margin the best concise video explaining it. I love science so I had those words in my vocabulary, but did not quite understand their relations and origins. Thanks for that! Sad to see it does not have much views, this is a pillar for further understanding of the conclusions we get and, of course, the universe itself.
Plants and some microbial life are producing oxygen gas in our atmosphere using the process of PHOTOSYNTHESIS, which has carbon dioxide and water as inputs. It is the detection of this process that should be emphasized if oxygen gas is found around an exoplanet. en.wikipedia.org/wiki/Photosynthesis
If I have ice cream or hot chocolate before I go to sleep my butt makes a hole in the ozone layer overnight if I have my window open. If I keep the window closed I eradicate all the spiders in the room. Lactose intolerance
duuuuuude, what an awesome video. I personally struggle with this problem of visualizing 3d wave shape. If anybody knows any page or info on this i would appreciate being linked.
A good way to visualise it imo is to imagine ocean water as a 2d slice of a 3d wave. For light, if there were only one source it would be a perfect sphere in the EM field.in our daily lives, though, with multiple sources of light and matter for it to refract and reflect off of its likely that the entire field is a chaotic mess of peaks and troughs with orderly patterns appearing along straight line paths
Why is uranium reactive but gold is not? I understand gold is relatively inert because the nucleus is big enough that the electrons approach light speed. So what about even heavier elements ?
I don't get your point of oxygen. Why would a planet's atmosphere necessarily change without life and therefore if a planet's atmos is in a steady state it implies life.
Oxygen is very reactive, meaning that the supply of O2 molecules will dwindle over time, as the molecules react with other substances such as minerals and metals. Therefore, only a steady supply produced by living things can sustain atmospheric oxygen for extended periods of time.
I’m a Chemistry Undergrad and I’ve forgotten everything over the summer. This video was a great refresh of many concepts though!
Good luck for future bud!

Me too. Which chem class are you in right now? I’m in second semester of Orgo it’s going well
Kamari Weaver I currently study multiple classes. This semester I’m doing: Organic, Computational, Quantum, Spectroscopic, Physical, Inorganic and Matter States. It’s a lot😅
This conversation is very interesting and inspirational; all the best with your studies everyone!
Already know all about this stuff, but your animation and super clear explanations still engage me. You really are a fantastic science communicator

I like your use of electron clouds changing as the electron jumps to a higher energy state -- rather than the typical orbit radius. Well played!
Thank you for the videos you do, man. Great job, useful for the humanity. It's a shame it has not so many views yet.
Purrfect animation and content🔥🔥worth the wait ❤️
I like the way it is presented and explained, so much easier to understand what's actually happening in context of real life.
All you had to say was “light behind the gas” and everything clicked. I wish my professors could clarify small details like this, it makes it so much easier to understand

Could you use spectroscopy and validate Unified Field Theory?
Can you do map of 'accounting'...I guess?Please.
I been thinking of making some instant noodles the whole time thic video has been playing then soon as you said Ramen I knew it was a sign 🍜❗✅
Cute animation
Maybe that's why the aliens are finally here. It wasn't me!
Farts . . . or decomposition, but farts is a better way to begin a lecture.

You left out BEC and laser cooling.
🤔 But what's the wavelength of brown? 🤣
Last time I was this early, the doctor told me to go back inside my mother's womb.
u get a like for the alien farts
Spectral line are vertical and double slits are vertical. I'm holding this presumed association against all you people.
