Serious opinions about this new browser?

And I want honest opinions and not those entirely based upon the fact that a past iteration of the engine was not good. Like all things, they can improve or get worse.

It's garbage.

It's trying entirely way too hard to be 'good', also it spawned an endless cascade of edge jokes, and I am not fine with that.

let's say i have the materials and technology needed to create a biomechanicaL warbeast based on a cicada. i want it to be able to blast out 194 Db waves of pure fuck-you-up. but also be able to use different frequencies and amplitudes of sound for different things too.

so, what's the best way to go about making it?
how would it work?

I want to learn mathematics. The next year I'll start a career of Pure Mathematics and I have a lot of years (5 aprox.) of neet. I'm looking for books to learn the topics about Mathematics in High School, alegbra and trigonometry, what else? If you can give me reference, please.

Any textbook will really work. Khan Academy is a good online source for getting ahead. Best of luck

Anonymous 16/10/14(Fri)12:54 No. 16366 ID: 1f1505

You will want Calculus, Linear Algebra, Differential Equations, Partial Differential Equations, Discreet Mathmatics, Complex Variables, Proofs, and Abstract Algerbra. There may be others but I can't think of them right now.

Yooo, OnChip is maybe considering doing a crowdfunding thing for making a Devboard for a RISC-V MCU. Sounds kind of expensive at their estimate of 90 dollars a board, but I'm interested in RISC-V and if they do it I'mma get one. Curious if the chip will be packaged or if it's going to be wirebonded directly to the board like their current prototype board... https://twitter.com/onchipUIS/status/785328697133953024

microscopic telescope Anonymous 16/07/22(Fri)21:09 No. 16346 ID: f55268 [Reply]

I just wondered, I have never heard of a microscopic telescope. By this I mean a device along the lines of a large nature-style camera lens or traditional telecope that is able to zoom in to the target area of a physical item and produce a 3d environment of that area through the lens? Surely theres an infinite amount of detail from a physical item We have all this advanced astronomical technology these days to look at things that lie in the distance. What would happen if technology was put into microscopic telecopes thanks everyone

TLDR: a lens of intricately layered magnifying glasses that self multiply

>microscopic telescope
What do you mean? A telescope of microscopic proportions, or a telescope able to detect micro-scale features of objects at astronomical distances? Judging by the rest of your post, I'm going to assume the latter.

>produce a 3d environment of that area through the lens
What? What microscope or telescope is able to do this? All a scope does is take a cone of light and focus it to make it appear larger, and thus easier to see to human beings (obviously this doesn't apply to electron microscopes which work by entirely different principles).

>Surely theres an infinite amount of detail from a physical item
No. Photons are discrete particles. It's possible for an object to be so far away that even if we convert the entire surface of the Earth into a receiving device, not enough photons from the object will hit the Earth during its entire lifetime to get even sub-meter resolution. To get sub-meter resolutions within a human lifespan for relatively close objects (say, 1 light year) would require astronomically large objective lenses. Or, the detection device would have to move really fast around the target, which would increase the resolution only in the dimension of motion.
For example, the LIGO experiment, which is believed to have detected gravity waves from the black hole at the center of the galaxy, uses "lenses" (they're not actual lenses, but they're analogous) with a radius of 4 km.
