Sup /sci/ - engineer-fag here, I need some help here

I need to come up with a mathetical model I can cram into mapple for a wonky little shape here

I just can't figure out how I'm supposed to do this.

its basically for a squished circle that has partially flattened out on the ground.

the top half is an ellipse 0.8 meters high, 2.25 meters to either side.

The bottom half is mainly a long flat stretch with circular ends that meet with the ellipse, radius 1 meter.

I need a mathematical model for this.

I know the model for a circle is (x-h)^2+(y-v)^2=r, with h and v being the horizontal and vertical center point coordinates.

For an ellipse its (x^2)/H + (y^2)/V=1, assuming its centered at (0,0)

how the fuck do I split that up I can model the thing in pic related?

Gone are the days when we had to go to the library everyday or get into study groups with real people in order to learn the subject. But thanks to Google, now this just "google it xD xD" phenomena has infected virtually every aspect of our lives. It actually makes people more autistic because there is no need to ask for advice or help from real people anymore. Not to mention the rise in the number of brainlets.

So I have something called MALADAPTIVE DAYDREAMING DISORDER [ = ((ADD - OCD)/2)^1000000] which effectively means I CAN'T FUCKING THINK. Whenever I'm doing something ungrounded in the surrounding objects (like thinking as opposed to reading) I can't fucking help but drift away.

Math and physics are my passion, so finally I decided to just skip exercises - which take me fucking forever - and just read the material. Now I'm obviously not planning on being like this forever and am already noticing the effects of meditation, but how much am I missing here? I'm gonna read the solutions to problems as well - at least to pass the fucking tests.

Anybody with the same problem? How are you coping with this shit? I'm not gonna just give up and be miserable doing some bullshit for the rest of my life, I'll tell you that much.

Our wait has finally ended! Crash Course has begun to produce a sociology series, and it is a fairly well-informed one.

Modern university education:
>Have to configure daily schedule such that one attends a variety of lectures which typically have suboptimal timing
>Have to take a shower and look presentable
>Have to take the time to commute to campus
>Must incur transportation costs to do this
>Increased time on campus elevated food costs as one will inevitably need to buy lunch
>Have to do laundry more frequently, costing time and money
>Arrive at lecture
>Professor isn't prepared
>Peers are loud or smelly or somehow distracting
>Lecture room is uncomfortable
>Professor spends an eternity scrawling some illegible derivation on the blackboard
>Somebody asks some retarded question, wasting more time
>Professor realizes he made a mistake and has to do redo part of the derivation
>The sum of the lecture's material could be learned in much greater detail in less than 20 minutes of attentive reading
>Instead nearly 3 hours of my time is wasted
>Repeat ad infinitum

If engineering is a field with high amoubts of intellectuals why can't they design a toilet that doesn't clog everytime I poop?

Any CRISPR fags here? How many years of studying will it take me to be 100% able to understand to the date discoveries in the field? I've done basic biology/ chemistry, but I'm a physics major already.

I'm just really interested in CRISPR, and I'm curious to know whether or not the time it takes to master this is anywhere near what it would take for CS/Physics/Math etc.

Thanks guys

>This igloo— er, house —is in Webster, New York, just outside of Rochester. The area is one of the snowiest in the country, thanks to freezing winter temperatures and the moisture of the nearby Great Lakes. In the case of this prank of nature, high winds joined in the party and coated the house in layer after layer of ice.

>Photographer John Kucko captured the scene, and says the area has had some particularly nasty weather lately.

pen autism thread

Favourite pens?
I'm a big fan of the one in pic related
Cheap, really nice for writing maths with. Doesn't leak at all, doesn't spludge the ink, feels smooth but has just the right amount of resistance

all around 10/10 and it only costs like £1 for a packet

How about this then? We've got 'pictures' of a molecule now.
