In this course students will explore a wider vary of Algebra matters beyond the introductory degree. Topics will embody polynomials, capabilities, rational expressions, systems of equations and inequalities, operations with radicals, and quadratic equations. Emphasis shall be placed on developing an awareness of using mathematics as it exists on the planet at present. The platform includes the firmware, gadget drivers, an operating system, and typically a graphical person interface which, in whole, permit a consumer to work together with the pc and its peripherals . Platform software typically comes bundled with the computer. On a PC one will normally have …
Tiny caps can measure activity in lab-grown minibrains
Minuscule lab-grown models of human brains can be fitted with caps that measure their activity, just as electroencephalogram (EEG) caps record electrical signals produced by full-size human brains.
The minibrains are examples of organoids—three-dimensional clusters of living cells, grown in a lab, that simulate the structure and function of human organs so that researchers can observe how they develop. Researchers often genetically modify them with viruses or exposure to chemicals to study how they change in comparison to unaltered organoids.
Until now, scientists haven’t been able to study brain organoids beyond just a few cells. While the organoids are spherical, …
The Download: electric planes, and trans men’s fertility
This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology.
This is what’s keeping electric planes from taking off
What’s happening?: Startups are exploring how electric planes could clean up air travel, which accounts for about 3% of global greenhouse-gas emissions. The reductions from embracing electric flight could be significant—close to 90% fewer emissions for a battery-powered plane charged with renewable energy.
What’s the problem?: Today’s electric aircraft could safely carry you and about a dozen fellow passengers only around 30 miles, according to a …
This is what’s keeping electric planes from taking off
Startups are exploring how electric planes could clean up air travel, which accounts for about 3% of worldwide greenhouse-gas emissions. The problem is that today’s electric aircraft could safely carry you and about a dozen fellow passengers only around 30 miles, according to a recent analysis.
The limiting factor is the battery, in particular the amount of energy that can be stored in a small space. If you’ve folded your legs into a cramped window seat or been charged extra for overweight luggage, you’re probably familiar with the intense space and weight constraints on planes.
Today’s batteries don’t have the …
Why we can no longer afford to ignore the case for climate adaptation
This article was originally published on Undark. Read the original article.
In the late 1950s, Ian Burton, then a geographer at the University of Chicago, learned about a troubling conundrum with levees. These expensive and engineering-intensive strategies—which the US Army Corps of Engineers favored for reining in floods along big river floodplains—worked well for holding back intermediate amounts of water. But they gave people a false sense of safety. After a levee went up, sometimes more people actually built on and moved into the land behind it. Then, if an oversize flood eventually poured over or broke …
