The Theory of Relativity for Kids, Part 4 – Time and Space in General Relativity

einstein4Welcome back! This is the last part of the series on relativity. Today we’ll talk about how gravity effects time and space. You might want to look at last week’s post before you read this one. It explains the basics of gravity in General Relativity. Go back to the Theory of Relativity for Kids if you want to start at the very beginning.

Friday Roundup: Stem Cells to Brain Cells, Swallow Evolution in 30 Years, and Cold Sores That Treat Cancer

A monkey’s skin cells were transformed into stem cells, then implanted in its brain, where they turned into brain cells, wired themselves up, and took on normal function. We now have brain scans capable of measuring activity on the cellular level throughout the whole brain. Well…fish brains anyway. The universe is just slightly older than [...]

The Theory of Relativity, For Kids

einsteinSo you want to understand the theory of relativity, and you’re a kid? No problem. Let’s get started.

(If you’re a parent looking for some activities to help teach your kid, consider ordering Albert Einstein and Relativity for Kids: His Life and Ideas with 21 Activities and Thought Experiments. And if you’re an adult who just wants to understand relativity, there’s no shame in reading on.)

Friday Roundup: Arctic Camels, Wireless Computer/Brain Interfaces

This insect’s wings contain tiny nanostructures that actually tear bacteria apart, the first structure of its kind discovered in nature. Giant camel fossils in the arctic. Using nanoparticles, scientists deliver bee venom to HIV viruses, destroying them without damaging the surrounding cells. In related news, an infant was functionally cured of HIV using normal HIV drugs by [...]

Friday Roundup: DNA Precursors In Space Clouds, and a Star as Old as the Universe

I relayed the scientific consensus on global warming as presented by the IPCC in an effort to introduce some much needed dryness to the conversation. No opinions. DNA precursors are floating in interstellar clouds that predate our solar system. The White House is thankfully taking steps toward making federally funded science freely available to the public. Autism is positively [...]

The Scientific Consensus On Climate Change

desertDespite dispute in the media, the scientific consensus is almost unanimous: the world is getting warmer as a result of human activity. But the scientific consensus is so clouded by politics that it’s very difficult for the average person to figure out what’s going on. I’m sick and tired of this, so what follows is a (hopefully) refreshing taste of dryness on the subject. No opinions, just the scientific consensus.
