How did a cancer cell evolve from a dog? What the actual fuck?
https://en.wikipedia.org/wiki/Canine_transmissible_venereal_tumor
>Canine transmissible venereal tumors (CTVTs)
>is a histiocytic tumor of the external genitalia of the dog and other canines, and is transmitted from animal to animal during mating.
>It is one of only four known transmissible cancers
>Although the genome of a CTVT is derived from a canid (probably a dog, wolf or coyote), it is now essentially living as a unicellular, asexually reproducing (but sexually transmitted) pathogen.
>Scientific classification:
>Kingdom: Animalia
>Phylum: Chordata
>Class: Mammalia
>Order: Carnivora
>Family: Canidae
>Genus: Canis
>Species: C. lupus
>Subspecies: Incertae sedis
>Binomial name: Canis lupus

Wow, that just blew my mind. It is literally a dog cell that went rogue and became its own multiplying organism
almost sounds like the plot of an inspirational movie
>>
It's not that surprising. Evolution occurs due to changes at the genetic level and cancer cells have rapid changes. Those HeLa cells taken from a cancer patient in the 50s have like 80 chromsomes. They are clearly no longer human cells.
This shit is pretty cool though and I'd love to see its role in evolution.

Do I absolutely have to learn classical physics before quantum physics? I really don't give a fuck about how much work is done pushing a brick up an inclined plane or how much kinetic energy a ball rolling down a hill has.

Exposure to things like this
https://en.wikipedia.org/wiki/Hamiltonian_mechanics
is what you want from classical before qm.
>>
You seem to not know the difference between Newtonian and Lagrangian mechanics.
You can do without Newton, but you need Lagrange. Hamilton too. Without them, you'll struggle with the mathematics and never understand the physics.
>>
You need exposure to the concepts in a context where you can visualize what's going on. Once you start with QM you won't be able to do that anymore, so having a good feel for a lot of concepts becomes important.
You should be able to solve this.

I would recommend restructuring of the board by limiting discussion to certain fields in Mathematics,or Chemistry(Pending better ideas). Also the censor posts about Universities or Career shaming because, while valid points are made in those posts, the nature of the posts are unproductive.
Fields like physics are prone to lay-people trying to express their views on complicated subject matter like quantum physics(sounds cool and sophisticated doesn't it?). The same goes for Computer Science and machine learning/AI.
I need your thoughts on this as long as you're not a dick about it.

Would anybody mind explaining this formula please? I need to hash a word but have no idea what the value equalling to ASCII is

>>
>>7962016
m=Athens is in Greece
m_1 = ASCII value of A
m_2 = ASCII value of t
m_3 = ASCII value of h
etc.
What do you not get?
>>
>>7962021
But where does the mod 13 come into the equation?
>>
>>7962027
The ASCII values are numbers.
You take those numbers mod 13.
let's take for example that this theoretical 2d space is perfectly aligned for the sake of argument. directions of orbit and speeds are drawn (poorly). is there any point of the blue sphere's orbit where it is moving slower than the body it is orbiting relative to the larger body's own orbital speed? ie, is the figure in black ever roughly true? pretend all orbital speeds are static.

....is 108,000 km/h ever less than (792,000 km/h - 108,000 km/h)?
umm
yeah?
>>
>>7962037
that's not what i'm asking. is the speed of the blue object equal to 200 km/s - 108 km/h at that spot in its orbit relative to the orange object's velocity? ie. at that point in its orbit is it going slower relative to the larger body's own orbit around the anus?

[math] AA^TA=\frac{n}{3}A [/math]
How many solution are there to this? Assume A is a nx3 matrix.
Is there any way to figure it out?

>>7961975
Yeah. Math always finds a way.
>>
A * At * A = (n/3) * A
A * At * A * At = (n/3) * A * At
(A * At)^2 = (n/3) * (A * At)
A*At = (n/3)
>>
>>7962022
Illegal, AAt is not invertable if A is non-invertable, and A can only be invertable when n = 3; which means AAt cannot be a scalar. Instead it would be only true when At is its own inverse.
If you're not actively doing scientific research why do you feel qualified to post on this board?

You're an ass.
I USED to do scientific research and have published papers in more prestigious journals than you ever will. But according to you, I should not be posting here?
If you were doing REAL scientific research, you would not have time to waste posting here. Go back to your little dreamland.

If light is made up of photons, but X-rays and ultraviolet etc are not, but they are all the electromagnetic spectrum, when does there stop being photons? Do the boundaries of visible light (violet and red) have less photons than the other colours?

>when does there stop being photons?
What? Explain what you mean here.
>>
>>7961692
I apologise if my wording is wrong
What I'm trying to say is, visible light is made up of photons yes? That's what we're taught, but we're also taught that it's part of the electromagnetic spectrum, and I'm assuming that X-rays and ultraviolet and microwaves are not all made up of photons, yet the visible light is.
I'm lost on where it stops being made up of photons and starts being made up of something else

Take a penny.
Declare to yourself that if you had this penny, graham's number's of times then you'd have graham's number's of pennies.
Now Graham's Number exists in the real world and your penny represents 1/Graham's number
