It's Puzzling That We Still Don’t Know How Airplanes Fly!
Watching a plane take off is truly amazing, but the secret is that we don’t fully understand how airplanes fly. While the Navier-Stokes equations theoretically describe the motion of fluids like air and can explain lift, solving them is exceptionally difficult. This difficulty is so profound that in 2000, the Clay Mathematics Institute offered a $1 million prize for solving these equations, as part of their 7 Millennium Problems**.

Which came first, the chicken or the egg?
Просмотров 11014 часов назад
Which came first, the chicken or the egg? The answer is: the egg came first. Scientists believe this because the first true chicken began its life inside an egg. Eggs are where small changes, called genetic mutations, happen. These mutations are what allow species to evolve over time. In the case of chickens, this means the first true chicken started its journey within an egg laid by its almost...

How Our Desk Feels Solid, Even Though It's Mostly Empty at the Atomic Level
Просмотров 2 тыс.День назад
Have you ever wondered how your desk can feel solid, even though it's made up of atoms that are mostly empty? It’s a mind-boggling concept that challenges our everyday understanding of what "solid" really means. Atoms, the tiny building blocks of everything around us, are surprisingly empty. Even though they make up all the solid objects we see and touch, their structure is mostly vast, open sp...

Within Seconds at Most: From Massive Star to Neutron Star or Black Hole
Просмотров 824День назад
The time it takes for a dying star to collapse into a neutron star or black hole is one of the most misunderstood aspects of stellar death. Many assume that such a profound transformation unfolds over days, years, or even centuries. The reality, however, is astonishing: the process occurs almost instantaneously, taking mere milliseconds to seconds. This rapid transformation vastly outpaces the ...

Not all eggs come from chickens and the first eggs were an evolutionary trait of a parasite that lived in fish millions of years ago called Sporomusa.
How can a table be solid if quantum theory says atoms don’t have a specified position but rather a spatial probability distribution dependent on the total energy of the system…
Probably because of the electric field propagating from our matter and the matter that makes up the table the electric charges repel ?
nice video brother👍
I love this video.
Im very happy to have found this channel. Keep up the good work!
Cool
The magic is Van der Waals.
Your videos are great man. You 100% deserve more subscribers and views!
Great video, thanks!
👍👍
I will explain these behaviors in videos soon. Until then, think about a large group of of atoms compressing one atom. It would become part of the group. I doubt that the nuclei remain outside of the electron shells. Another important point is that, just because there may be no "thing" between a nucleus and its electron shells, it doesn't mean that there is nothing there! How do you understand what the interior of an atom looks like? Stop picturing the protons and neutrons as little plastic balls.
Whats your name?
Great !
No one can tell what life was b4 planet Earth
Spectacular background artwork.
That thumbnail is diabolical
The more we know the more 'rare earth hypothesis" seems to be the case.
What my Grandmother told me in the 1950s was ruclips.net/video/Wmd_Os2z_u8/видео.htmlsi=QDTlCi8A0dgCl24d
three words for ya kid. Vibes of Cosmos. catch some reality
Are you a biologist?
I always asked myself this question. Thank you !
15% of trillions is not rare it’s uncommon at best
Very fascinating, thanks for the video.
Why is the thumbnail ai garbage
Nice Video man! Next time maybe a bit longer? :)
Good topic
Lets thank gru for making this video.
Antarctica is endlessly interesting.
It is so cool that those models show the field of atoms and their polarities. Super cool.
How about some AI voice over? :)
thats some of the worst advice
@@holodrio1719 in general - yes. in this case - no.
Nah dude that’s not nice
@@Mr_42. if it helps you my english is also not good enough for youtube
@@folkereicht5746 your english is too bad to understand him ;D
Antartica is great... Until they find something buried in the ice that has been there for over a 100,000 years and the pilot of a crashed ship nearby. Penguins and the sea dogs are cool though, no pun intended.
Very good video
Missed out man made deserts, that get plenty of rain but were over grazed and logged.
Humans don't have tails because they were created without tails.
But we have a tail, it's just vestigial
So basically, it is not more than just no rain. The reasons why there is no rain only differ...
Thanks for the video!
Desert👍
You make such great videos!! Thank you
Please, please, please never use an AI text to talk. It's refreshing to hear someone who English is not their 1st language not using AI.
why is the "mexican" bat has a scientific name "braziliensis"?
because one person decided to name it after Mexico and another decided to name it after Brazil (it exists in both countries, along with many others)
I smell the start of a rising channel. Subscribed!
life itself is. a paradox .. It defies the laws of thermodynamics
IS THAT AI ART?
I ended up getting into a rabbit hole of genes and their very specific roles, and ended up landing on genes + proteins that focus on eye development. This was exactly the type of video I was looking for!
At depths of 12 Km does the borehole instantly close/ collapse as it's being drilled out?
Why didn't any plants develop eyes? And how did anything that did develop eyes know that they needed eyes if they never had eyes? Evolution is a JOKE.
