You should be able to solve this.

All blue shapes are yes, all non, blue shapes that are not ovals are no
Yellow oval in the yes box, yellow oval in the no box
>tfw too stupid to figure that shit out
Crescent is yes
Yellow donut is no (?)
Blue arrow is no
How can we stop volcanic eruptions? More importantly, how can we stop pic related?
Build an enormous tube above it and aim the eruption at third world countries

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.
>>7962018
i'm retarded, is there anywhere i can learn more?
>>7962005
....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?
>inb4 engineers
>>7961695
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
>>7961685
>X-rays and ultraviolet etc are not
They are

What is the name of a divice that tightens around a 2mm string so that it cant be tugged and pulled though becuase its held in place
a coupler/saddle?
>>7961507
Held in place by friction to be more specific
>>7961531
Its like a cord stoper except unlike a cord stoper it only stops the cord when you pull on it
True?

What's wrong with doing maths with a pen? That's how it's always been done ever since there were pens or pencils.

If math reflects reality how come Graham's number is so large it can't even exist in our universe?
>>7961114
math doesnt have to reflect reality. Math is all about taking logic and making concrete rules for it.

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
What a good way for me to learn Algebra and Calculus?
I've basically forgotten everything from school except basic addition, subtraction, multiplication and some division.
>>7960864
I'm not the samefag
Maybe there's just more retards on here than you think
>>7960869
(You)
I'm in Calculus I and I still don't know anything about bases. Shouldn't I have learned them by now? Is there any hope for me in future math classes?
>>7960855
bases of what?
>>7960862
Not even me. I may be stupid but I know more than addition, subtraction, multiplication and division.
How does it feel being at the receiving end of your 'space colonization' fantasies? They do not want us, they want our planet. Can you imagine which 'technological infrastructure' it is that can be easily shut down to completely wipe out civilization as we know it and send the few that survive back to square one?

oh yeah hey let's skip all those nebulae and gas giants and asteroids and target THAT. ONE. PLANET. IN. PARTICULAR.
