Undergrad Escape of Hydrogen from the Earth's Atmosphere
Ok. Thank you for pointing that out. Could you elaborate the direction tho, please. And yes I made a mistake on alpha particles. Thank you tho- Seanskahn

Undergrad Escape of Hydrogen from the Earth's Atmosphere
Damnation. Ya. I do. I mean protons should also be blocked. Lol- Seanskahn

Undergrad Escape of Hydrogen from the Earth's Atmosphere
Alpha particles ( Hydrogen nucleii) should be deflected by Earth's magnetic field.- Seanskahn

Undergrad Behavior of a curved 2D sheet and a curved 1D wire under acoustic wave
Good day. We know how simple objects, such as 1D wires behave when a simple harmonic wave travels along a wire, or two wires knotted togethe.We also know what happens if you excite a circular thin disc with a single frequency. Are there some material I can read on, that considers the effect...- Seanskahn

Graduate Are there still open problems in classical wave optics?
I have been revisiting my notes from my 2nd and 3rd year physics degree - especially the ones covering Fourier Optics, and other classical wave optics - and it is quite rewarding to revisit the historical / exploratory aspect of the series of discoveries, that built the foundations of this... -
Minimal Values of Repeated Numbers for Desired Probability?
Homework Statement Let 0≤p≤1. Let there be k distinct numbers (they can be natural numbers) a1, a2, ... , ak, each repeating respectively b1, b2, ... , bk times. Let q < ∑r=1k br Determine the minimal values of b1 ... bk such that the probability of q numbers chosen out of ∑r=1k br numbers...- Seanskahn

High School Did Mars Once Have Flowing Water?
@ enthalpy, i am afraid, no. a lquid will take a round drop shape only when 1) either it has a high surface tension, and the medium it is on has a low adhesion (mercury and glass for example) - for lava on rock that is not the case 2) in microgravity, in Mars that is not the case either.- Seanskahn

Ocean salinity and its affect on surface tension
it could affect the evaporization of droplets produced by breaking spray and thereby affect the generation of marin aerosols.- Seanskahn

What happened to the mammoths of the ivory islands?
should the caracasses be transported to the burial ground by water, then you might want to guess the flow was torrential enough to carry them. the matrix of a sedimentary rock in torrential water is uneven, and random sizes of granules make such a matrix. if you see such kind of rockbed, you...- Seanskahn

High School Did Mars Once Have Flowing Water?
there is another factor coming to play, the temperature, and the erosion by lavaflow erosion is rather changing the chemical signature of the contact zone (consider that rocks are poor conductors), and often lava is more viscous than water hence flow is very very slow, hence you will not expect...- Seanskahn

High School Did Mars Once Have Flowing Water?
my two cents: Mars _does_ have a water cycle albeit *not* earthlike. What happens is that the polar cap, does not just melt, it vaporizes, releasing carbon dioxide and water vapor in the summer hemisphere, and that results in highspeed winds. this wind drives dust, and ice crystals and water...- Seanskahn

High School Radio communicattion in lower wavelength
Hi community. Once again, a stupid question: if radio waves are electromagneetic waves, generating an electric field in the antenna, then why can't one just shine visual light (also electrromagnetic waves) on same antenna and use that for communication? thanks s- Seanskahn

Graduate What Are the Commutator Relations Between Hermitean Operators A and B?
ok, found it For those who might want to know the answer, <A>, <B> are scalers, not operators, so they commute with each other, and the operators, A and B- Seanskahn
