Double integrala. The meme becomes real.

What if after I do the first integral the resulting integral is incomputable?

What the fuck did you just fucking say about complex numbers, you little bitch? I’ll have you know I stopped caring about math when I was introduced to the concept of imaginary numbers, and I’ve been involved in numerous secret raids on Al-Gebra, and I have over 300 crocks of shit. I am trained in equations that can only be solved by inventing numbers that can't exist and I’m the top math deity in the entire US academic forces. You are nothing to me but fucking wrong. I will wipe you the fuck out with math the flaws of which have never been seen before on this Earth, mark my fucking words. You think you can get away with saying that shit to me over the Internet? Think again, fucker. As we speak I am contacting my secret network of algebra solutions across the USA and your IP is being traced right now so you better say "the correct answer is whatever the correct answer is", maggot. The math that says the pathetic little thing transcribed to words. You’re fucking dead, kid. I can be anywhere, anytime, and I can mark you wrong in over seven hundred ways, and that’s just if you write it down in english instead of ancient math runes. Not only am I extensively trained in unarmed combat, but I have access to the entire arsenal of the United States Logical Math Corps and I will use numbers that never lie to their full extent to wipe your miserable ass off the face of the continent, you little shit. If only you could have known what unholy flaws your little “clever” human construct was about to bring down upon you, maybe you would have held your fucking tongue. But you couldn’t, you didn’t, and now you’re paying the price, you goddamn idiot. I will shit complex numbers all over you and you will drown in it. You’re fucking dead, kiddo.

7th or 8th grade in Germany here, not sure which one it was we learned roots. It was not the teacher however, one of us wanted to take roots of negative numbers.

>people are taught about complex numbers in middle school
>they aren't taught about group theory until late high school or college
How does it make sense to teach people about something before teaching them about the subject that is required to understand it?

>>8764896
do a mass to volume conversion via the density of key brass or something

The mass could be easy to find, but I cant seem to find either a density or volume .

You're a high functioning retard if you think that something can be created from nothing

Why do people keep talking about a TV show like it has something to do with science?

>>8764422
you never defined g_1 and g_2 brainlet, only a single function g

and yes f is a monomorphism because if
f g_1 = f g_2 for two functions g_1, g_2 from C to A then
f g_1(c)=f g_2(c) for all c in C
since f is injective this implies g_1(c)=g_2(c) for all c in C

Reading. Will reply once my brainlet mind thinks this through

shouldn't it not be something larger of a network than just speech? otherwise are newborns/deaf people not conscious?

>>8764414
mute people*

>>8764411
first you have to define what consciousness is

Get the data together and present it to the dean or the principal/rector. Tell them that you suspect fraud. You can also contact the journal that published the professor's results.

Ask your professor to help you get Y out of X. If your professor can't get it to work either, then you have a nice "X doesn't Y after all" paper.

>>8763816
Fraud need not enter into it, and likely doesn't. Fuckups are very common in science, that's exactly WHY you do replications.

Werner von Braun similarly did well in his technical and science classes, and poorly elsewhere, and he got to be a Nazi and build moon rockets, and had all the pussy he could use.

So do not despair.

Picture a tablet that you can fold into the size of a phone and put away in your pocket, or an artificial skin that can sense your body's movements and vital signs. A new, inexpensive sensor developed at the University of British Columbia could help make advanced devices like these a reality.

The sensor uses a highly conductive gel sandwiched between layers of silicone that can detect different types of touch, including swiping and tapping, even when it is stretched, folded or bent. This feature makes it suited for foldable devices of the future.

"There are sensors that can detect pressure, such as the iPhone's 3D Touch, and some that can detect a hovering finger, like Samsung's AirView. There are also sensors that are foldable, transparent and stretchable. Our contribution is a device that combines all those functions in one compact package," said researcher Mirza Saquib Sarwar, a PhD student in electrical and computer engineering at UBC.

The prototype, described in a recent paper in Science Advances, measures 5 cm x 5 cm but could be easily scaled up as it uses inexpensive, widely available materials, including the gel and silicone.

"It's entirely possible to make a room-sized version of this sensor for just dollars per square metre, and then put sensors on the wall, on the floor, or over the surface of the body -- almost anything that requires a transparent, stretchable touch screen," said Sarwar. "And because it's cheap to manufacture, it could be embedded cost-effectively in disposable wearables like health monitors."

The sensor could also be integrated in robotic "skins" to make human-robot interactions safer, added John Madden, Sarwar's supervisor and a professor in UBC's faculty of applied science.

Researchers at the University of Alberta have developed a new method of controlling biology at the cellular level using light.

The tool -- called a photocleavable protein -- breaks into two pieces when exposed to light, allowing scientists to study and manipulate activity inside cells in new and different ways.

First, scientists use the photocleavable protein to link cellular proteins to inhibitors, preventing the cellular proteins from performing their usual function. This process is known as caging.

"By shining light into the cell, we can cause the photocleavable protein to break, removing the inhibitor and uncaging the protein within the cell," said lead author Robert Campbell, professor in the Department of Chemistry. Once the protein is uncaged, it can start to perform its normal function inside the cell.

The tool is relatively easy to use and widely applicable for other research that involves controlling processes inside a cell.

The power of light-sensitive proteins, Campbell explained, is that they can be used to study the inner workings of any living cell. For example, optogenetic tools are widely used to activate brain activity in mice.

"We could use the photocleavable protein to study single bacteria, yeast, human cells in the lab or even whole animals such as zebrafish or mice," explained Campbell. "To put these proteins inside an animal, we simply splice the gene for the protein into DNA and insert it into the cells using established techniques."

The gene for the photocleavable will be made available on Addgene, providing access to other researchers and scientists.
