Can you explain to Neil & Chuck that a VPN doesn't prevent sites to track you though? They really are clueless about the actual functionality of their sponsor... Thanks a lot!
@@RafiGish Except that criminal scammers utilize VPN's all of the time to avoid being tracked. A vpn can block tracking technology. It is why internet criminals use a vpn. To avoid being tracked and located. All a website or ISP would be able to determine is that a person is using a VPN. And not every website or ISP are able to even detect that, much less track anything else on a system running a VPN. Where the risk actually lies in regards to VPN's is that the creator of the VPN can track your every single move. Many actually do so actively. Norton for example offers VPN service. Except they track EVERYTHING done while using the service. Talking passwords, home addresses, mother's phone numbers, who a user talks to online. The list is unbelievably long.
Consume the square root of the weight of one mole of carbon in drinks, then try again. If that does not work, multiply the previous amount by 1.5. By then the numbing should either fade, or increase to the point of no longer caring. Either way, just don't be driving for several hours. lol
I have to say thanks to y’all (Neil & Chuck) for this excellent content. We laymen are privileged to have such excellent educational content that’s entertaining as well
i think yr taking about atoms. those molecules wont stay the same for long as they constantly exchange atoms. watermolecules for instance are constantly exchanging hydrogen atoms with one another.
I'm so grateful for people like Neil and chuck to put so much effort into their craft but also taking the time to educate and entertain us. Great work guys. Keep it up
i know i may be alone in this but ive clearly understood the concept of mole in just 2 minutes of Neil's explanation than all the combined classes of my chemistry teacher
Only this corner of the internet will truly appreciate how precious it is that, in all of time and space, we exist at the same time as Startalk. A wonderful gift to us all.
I think he got ahead of himself and did not catch the mistake before moving on. lol Did your brain scream at you too when you heard it? Or was it just mine I heard having a fit? lol
It has been a while, even though I am a long time subscriber, since I have watched a social distancing version of StarTalk. Reluctantly, this is the first episode i have turned into. And I must say it gives me and mine much hope in adapting to a new method of interaction and exchange of ideas. Watching the prestigious teachings of Dr. Tyson and intellectual yet comedic commentary of Mr. Nice assures all of us we shall continue in our ambitions to experiment, learn, teach, and repeat.
It would be interesting to see an animation of how a single breath of air spreads across the whole world. Does that happen in 10 years or does it take 10,000 years, or maybe even longer.
Spent some time recently on FB learning about the English women who discovered the basic building block of the universe. Her, along with many other women, have been left out of the stories of discovery in many STEM fields. I remember the women who actually first saw the double helix of DNA, or the women with he slide rule that checked NASA calculations for early space flights. How about shedding some light on some of those folks in your series?
The thought of tools being able to manipulate atoms and assemble molecules as we see fit immediately gave me goosebumps! Anyone else thinking of new materials that may have properties we can't even dream of yet? Really exciting stuff! Thanks a lot for Star Talk, you guys are awesome
@@cristineevangelio5223 One more reason to dig deeper :) My last real contact with the periodic table was about 20 years ago in school, so...I'm not surprised that a lot has happened since :) Thanks for the heads up
Thank you so much for bringing my attention to "quantum construction" on a molecular level. This has potential on a macro level after optimizing it on a micro level. This process could be the missing piece for the next gen computer, food science, and environmental stability. Great episode!
I refuse to believe there are actually any people alive who really believe the earth is flat. Flat earthers are just attention seekers trying to get attention.
@@JohnyG29 i mean if a religious person believes some sky daddy created earth and humans came from adam and eve. Flat earthers aren't that radical after all.
The smallness of molecules highlights the fundamental scale at which chemical interactions and processes occur. Despite their tiny size, molecules play a crucial role in shaping the properties and behaviors of matter, influencing everything from biological functions to material science. Their small scale necessitates sophisticated techniques to observe and manipulate them accurately. How might advancements in nanotechnology and molecular imaging further our ability to understand and harness the power of these minute building blocks of the universe?
11:51 CORRECTION; atomic number of carbon is 6 not 12. Atomic number is the number of protons in the nucleus of an atom. What he was referring to I guess is MASS NUMBER of carbon
The mole is a concept that didn't originate until 50 years after Avogadro's death. The reason Avogadro is the namesake of the unit, is because of his contribution to the ideal gas law, that the volume is proportional to the number of molecules, regardless of the substance identity. In other words, the idea that the R in the ideal gas law is a constant, rather than a substance-specific value. Avogadro's idea that population of gas molecules is what ultimately matters to gas laws, is why he is the namesake of the number of molecules in a mole.
Which is why I don't want to be buried or stored in an urn when I die. Every molecule that established my body no longer belongs to me, and shall all be returned to the Earth.
I have been playing around with fog water droplets, and it seems to me that it takes more energy to put the fog droplets back togather in one large mass then it does to produce the fog in the first place. Some astronaut said that tiny water droplets tend to bounce off one another because of a coating of air around the droplets. Is this similar to fusion teck ?
Thank you for being here to take my mind off of all that is going on right now..I appreciate it ❤ I know this was 2+ years ago but it's helping me now 😊
just did a crosscheck for my curiosity, there are 1,260,000,000,000,000,000,000 L of water in the world, divide it by 200ml (a cup) = 6.3e+20 cups. In a cup of water (200ml), there are 6.688e+24 h2o molecules. So yes there are more water molecules in a cup than the cups of water in the world. Please correct me if i'm wrong.
Something that has been bugging me: is there any thing in our universe with a size that would be in a threshold where it can "move" between quantum mechanics AND relativity?
It has to be a long enough time for the molecules to spread everywhere, so you may not have. That's why he only brought up historical figures from hundreds or thousands of years ago.
Avogadro's number is essentially the number of atoms or molecules in N grams of a substance, where N is the mass of one atom or molecule of the substance in atomic mass units. An atomic mass unit is approximately the mass of a hydrogen atom. So an Avogadro's number (called a "mole") of carbon-12 atoms weighs 12 grams. (Carbon-12 has 12 protons and neutrons, and therefore weighs approximately 12 atomic mass units.) Similarly, one Avogadro's number (i.e., a mole) of water molecules weighs 18 grams. (That's about 3/5 of a U.S. fluid ounce.) That's because each molecule of water weighs 18 atomic mass units, because each molecule contains two hydrogen atoms (at 1 amu each) and one oxygen atom (which weighs 16 amu). So, how many water molecules are in 18 grams (a mole) of water? 6.022 × 10^23. That's 602 billion trillion molecules! 🤯
Another factoid to go with this video. The reason helium balloons steadily deflate is because a helium atom is soooo small, the smallest thing in fact because hydrogen is diatomic, meaning two hydrogens are almost always attached together, Making them bigger than one helium atom. Helium being a noble gas is satisfied alone. This means helium is so small it literally travels through the “airtight” fibers of latex. Now that’s crazy!
I do appreciate how small molecules are but that is only considering non-repeating molecules. There are salt crystals the size of houses that are technically molecules. Ice and all other crystals are molecules too but impurities may cause some argument with this point of view.
Reminds me of a quote from a TV Show called Life in the Episode Fathingale. We are none of us alone. Even as we exhale, it is inhaled by others. The light that shines upon me, shines upon my neighbor as well. In this way, everything's connected to everything else. In this way, I'm connected to my friend, even as I'm connected to my enemy. In this way, there is no difference between me and my friend. In this way, there is no difference between me and my enemy. We are none of us alone.
If you assume 1 cup is ~ 240 mL (so about ~ 240 grams). Molar mass of water is 18 grams per mol so 1 cup is about 13.3 mols of water. That’s 13.3 * 6.02*10^23 molecules of water. How in the world did you only get 100 molecules in 1 cup?
I am wondering if the large and small work about the same. In specific, are electrons, protons, and neutrons about at the same relations as the sun and planets. Is the space between about the same like it's a fractal? To say this another way, Is the sun and Neptune a decent example of the relation as a proton and electron.
