In which John Green teaches you about the European Renaissance. European learning changed the world in the 15th and 16th centuries, but was it a cultural revolution, or an evolution? We'd argue that any cultural shift that occurs over a couple of hundred years isn't too overwhelming to the people who live through it. In retrospect though, the cultural bloom in Europe during this time was pretty impressive. In addition to investigating what caused the Renaissance and who benefitted from the changes that occurred, John will tell you just how the Ninja Turtles got mixed up in all this.

The students at Ron Brown College Preparatory High School are “kings.” All freshmen. All young men of color. All determined to change the dominant narrative about young black men in Washington: too many read below grade-level and won’t graduate high school. This new public school in Washington D.C. opened its doors in August 2016 and is radically different. Not just because it is a public school for boys, but because it's designed specifically to meet the needs of D.C.’s young men of color. The school’s principal and the majority of its teachers are black men. They begin each morning in a school-wide circle, navigating conversations that include neighborhood violence and police shootings, protest and poverty. Many schools do one or two of these things, but few do them all – and with the conviction of Ron Brown’s staff. For the past year, through a partnership between Education Week and NPR, we visited Ron Brown weekly -- and some weeks, daily -- to witness the birth of this new school and to see how its staff tackles some of the toughest challenges in education today. We spent hundreds of hours there, from the earliest days to the last bell.

This activity focuses on the use of graphene in organic fibers, and their applications in organic electronics, e-textiles and wearable technologies. Students learn about the properties of graphene—a unique form of carbon—and how graphene-based fibers are fabricated, how to measure resistance, how to calculate resistivity, and how a material changes its electrical properties. Students also learn about the importance of defining design parameters, which is an important concept in the engineering design process. Students create graphite-based fibers using sodium alginate as the medium and a calcium coagulation bath, which is similar to the way in which graphene-based fibers are created in engineering research laboratories. Students then determine the factors that contribute to resistivity and vary these parameters to optimize fiber resistivity.

Difference between Organic and Inorganic Compounds
Organic compounds contain carbon. There are at least four important organic compounds, lipids, proteins, carbohydrates, and nucleic acids.
Inorganic compounds do not contain carbon and usually are more simple compounds.
There are some compounds that contain carbon and are inorganic like carbon dioxide.

In 1958, farmers digging for bat poop in a Chinese cave stumbled on something way stranger—a fossilized skull that would baffle scientists for decades. At first, experts thought it was a Neanderthal, but new micro-CT scans have revealed a twist: it doesn’t fit neatly into Neanderthals, Homo sapiens, or even Homo erectus. Instead, Maba 1 is a mash-up of features—part this, part that, and part “what on Earth is that?” The skull’s brain size is surprisingly modern, but its structure is just too weird to belong to any known species. Some researchers now think it might represent a completely unknown human lineage that lived in Asia 300,000 years ago. Join us as we uncover the mystery of Maba 1 and what it tells us about our strange, twisted evolutionary story.

Calculus isn't just abstract mathematics, it is an incredibly useful tool. Here I show you how to use it to derive the volumes of 3D shapes. Check out my posters here https://store.dftba.com/collec....tions/domain-of-scie

This was the first example that really opened my eyes to the real value of calculus. I learned it in university in my physics department mathematics class, and it was just the beginning of a long journey of me wielding calculus at all sorts of practical problems in physics, and it gave me the power to see where the equations of physics came from, rather than just having to learn an memorize them. Awesome!

This calculus video tutorial provides a basic introduction into logarithmic differentiation. It explains how to find the derivative of functions such as x^x, x^sinx, (lnx)^x, and x^(1/x). You need to take the natural log of both sides of the equation and perform implicit differentiation to find dy/dx. You need to be familar with product rule for derivatives and properties of logarithms.

A relative pronoun is a word like “that” or “which” or “who”, so a relative clause is a clause that begins with a relative pronoun. In the sentence “The dragon who breathed blue fire has retired,” “who breathed blue fire” is a relative clause. Learn more about these constructions by watching the video!
