Perhaps the idea of plus and minus infinity at the edges of the Cartesian plane is not right at the true axiom of infinity is in the polar coordinates [math] \big(r,\theta\big) [/math] so that there is no such thing as minus infinity.
I basically need to have a concise game concept that you can make out of normal arts and crafts supplies. My topic is mole conversions.

Vaguely related: I recently built an Excel sheet which tests knowledge of the entire table, primarily names, symbols (abbreviations) and types/group names (alkali metals, transition metals etc).
The first sheet (pic related) is where data is entered/populated. The third sheet, which is locked/protected, is the master answer key. The second sheet is a conditional format which shows at-a-glance how you did. If corresponding cells in sheets 1&3 have equal values, then the corresponding cell in sheet 2 is Y/green, else N/puke red.
Overall I got something like 95% when I played my own quiz. I think I'll apply this quiz format to other things I want to study/memorize.

why not make a game about the final frontier: chemical space. Chemical space is the space of compounds that are possible.
https://www.chemistryworld.com/opinion/chemical-space-is-big-really-big/7899.article
https://en.wikipedia.org/wiki/Chemical_space
Chemical space is so big that if we were able to synthesize every compound with a molecular weight up 500 in 10 mg vials, that we would need more matter in the visible universe.
You could like legitly make a game where you put together molecules using the construction system that was used to make any of the GDB virtual chemical databases.
So I have the option to get a master's and a bs in financial economics in 4 years total.
The course set focuses heavily on econometrics and is professionally focused.
Has anyone here done an economics masters program and would like to share their experiences?
economics is the biggest meme. federal reserve has 700 economists working for them and they have nfi what they are doing.
as jim grant says here 'they either need 701 or none'

According to some balding Lebanese author who pretends that "you can't predict nuffin" is a deep statement, economist are used to rationalize decisions to an audience, rather than advise decision makers

How long would it take to start space travel that could bend gravity in such a way that you could move 100 light years away from earth, and witness your conception with a telescope? E.g using the Alcubierre drive, could I theoretically see inside my house in the past by just traveling lightyears away and capturing the light with a huge telescope?
Would such a thing be feasible in the very distant future? if so, how long do you predict?
>>8968475
>ould I theoretically see inside my house in the past by just traveling lightyears away and capturing the light with a huge telescope?
disregarding trivialities, such as the complete lack of understanding, as to how to even begin conceptualizing a working Alcubierre drive, and the impossible size of the telescope required to let you look into a window on earth from 100 light years away, yes, it's all totally possible
Why don't we just DRAIN the ocean surcace so that it holds more water and the populated areas won't get sunk in global warming?
Instead of wasting this nonsense in one-of posts yo /sci/, you should make them into Troll Physics images and post them on /n/, so your wit can be immortal.
Republicans have all this under control.
The plan is to have Jeff Sessions and
Ted Cruz's dad stand at the shoreline
with bibles in hand. As the sky
darkens and the water rises they will
raise their left hand holding the bible
and command the Seas to settle, and if
that fails, plan B is to run like hell
and to blame Obama.
>>8968332
Actually I just calculated the minimum theoretical cost of pumping the world oceans 1m lower, by pumping the water up to a 500m height, and at 55$/MWh and 100% pumping efficiency it costs a mere $27 trillion.
That does sound like a lot but it's really not that much, the biggest problem is finding where the hell to put all this water. Maybe Australia or Africa could keep it trapped for long enough.
Hi /sci/,
Anyone could explain or point me to a place where I could read about causes of the mid-pleistocene transition? (precisely, the cycle 41->100 change)
I'm in the middle of a conversation with a "AGW sceptic", and he's trying to refer to that event as a possible proof that the cloud forming due to deforestation may be a stronger cilmate changer than CO2 (??), that's why I'm asking.
Cheers!

The argument makes no sense since AGW is not over thousands of years. Saying so-and-so caused the MPT tells you literally nothing about what factors are strong in current warming over a hundred years.
>>8968347
For AGW yes, but one would hypothetise that it's relevant for GW in general and may heavily affect it now, during the existence of human civilisation.
I'm looking to visualize the connections between different properties, in a data-set like this one:
A: green, red
B: green, blue, red
C: green, blue
D: red
E: green, blue
F: green, red
And I want the visualization to connect the different properties by lines, preferably, with the line thickness increasing with the amount of times each property is on the same line as an other property. You get this kind of web structure, and you get a grip of what kinds of properties are often correlated/connected with each other.
What is this called? I know I've seen it before here and there.

So I just pulled this gross thing out of my head
Had a wisdom tooth pushing against it for ages
Growing sideways into it
Is there anything I should or shouldn't be doing now
I rinsed with salt water and moth wash over and over
Didn't really bleed much at all
Advice
>>8968165
looks like a dead tooth, nothing will happen to you because it probably came out a long time ago judging by the look of it, and it stood loosely there. And the hole where the tooth was positioned probably healed over time so it didn't bleed so much. Probably should go to your dentist just to check up
>>8968265
I'm gonna hit dentist
Just wanted to get a little insight
Thanks there

Are you british?
Is there any good resource you know of, that helps getting an intuitive understanding of the simplex method and helps me implement it?
My current understanding ends when the vertices are selected and optimized out of the tableau.
Also I want to be relatively quick (~ max 2 days of work).
>>8968086
Learn about interior point methods instead.
They are easier to understand (basically just Newton's method), faster in practice and can be generalized to work for nonlinear problems too.
>>8968096
I am already somewhat familiar with this, but this is for an assigment. So there is no way around it. But this is the reason I want the "quick" way.

Is there any actual reason why we use the conventions "positive" and "negative" to describe charges? Are they actually descriptive of some characteristic of the charges, or is all that's actually important just expressing that they're opposites?
>>8968024
just convention of doing mathematics with them
>>8968024
clockwise and anticlockwise
>>8968024
>Is there any actual reason why we use the conventions "positive" and "negative" to describe charges?
Yes -- because their behavior is perfectly described in terms of multiplication of positive and negative numbers.
For example, here's the electrostatic force equation:
F = (k * q1 * q2) / (r^2)
In that equation, two charged bodies are represented as q1 and q2. If they both have the same sign, then the resulting force F is positive. If they have different signs, then the resulting force F is negative.
That result agrees perfectly with the fact that opposite charges attract (represented by negative F), and like charges repel (represented by positive F).

The magic cabinet contains infinite storage space, but each partition can only be accessed from its particular line of drawers. Furthermore, in a finite space, there is only room to access finite drawers. The drawers extend at 90 degree angles from one another.
If a magic cabinet is placed in the centre of a room 3 times the size of the cabinet, you can access 60 partitions, as a single drawer can be spiraled out around the cabinet for 8 partitions, in the other direction for another 7, and the method can be repeated for the other 3 drawers.
1. How many partitions can you access if the cabinet is in the corner of the room?
2. How many partitions can you access if the cabinet is in a room 5 times the size of the cabinet?
3. How many partitions can you access if the cabinet is in a room N times the size of the cabinet, where N is an odd number?

1: infinite
2: infinite
3: infinite
Why? Because, "magic".

I think the answer to 1 is 78.
