Karin Bojs: Spår av släktingar för miljarder år sedan I dag, närmare tre tusen år efter det att Första Mosebok först tecknades ned, finns en uppdaterad version baserad på vetenskaplig forskning. Den säger att universum – åtminstone den del av universum som våra instrument kan överblicka – uppstod för 13,7 miljarder år sedan och sedan dess har svalnat och utvidgats kraftigt. Vårt eget solsystem uppstod för ungefär 4,6 miljarder år sedan, från ett hett och roterande gasmoln.

The Truth about Vaccines Episode 1: Top Ten lies debunked This episode is sub-titled The History of Vaccines, Smallpox, Vaccine Safety and the Current CDC Schedule. I accessed the documentary by joining the email list. From there, I got a daily email with a link to watch today’s episode free for 24 hours. After the 24 hours, the episodes are available for purchase at the Truth about Vaccines website. The series is hosted by Ty Bollinger. Ty is a CPA.

Do-It-Yourself DNA Have you ever wondered how scientists get a sample of DNA from a plant, animal, or other organism? All living organisms have DNA. DNA, which is short for deoxyribonucleic acid, is the blueprint for almost everything that happens inside the cells of an organism — overall, it tells the organism how to develop and function. DNA is so important that it can be found in nearly every cell of a living organism.

SWR Tatort Mensch - Wunderwerk Immunsystem Die Sendung behandelt grundlegende Funktionen des Immunsystems, mit denen sich der Körper gegen Infektionserreger wehrt. Zur Aufklärung der Abwehrmechanismen haben die Forscher Ilja Metschnikoff, Paul Ehrlich und Emil von Behring entscheidend beigetragen. Historische Rekonstruktionen verdeutlichen, wie sie zu ihren bahnbrechenden Erkenntnissen kamen. Early Human Evolution: Early Human Culture Paralleling the biological evolution of early humans was the development of cultural technologies that allowed them to become increasingly successful at acquiring food and surviving predators. The evidence for this evolution in culture can be seen especially in three innovations: Tool Making Some chimpanzee communities are known to use stone and wood as hammers to crack nuts and as crude ineffective weapons in hunting small animals, including monkeys. However, they rarely shape their tools in a systematic way to increase efficiency. The most sophisticated chimpanzee tools are small, slender tree branches from which they strip off the leaves. These twigs are then used as probes for some of their favorite foods--termites and ants. It is likely that the australopithecines were at least this sophisticated in their simple tool use.

Calling Bullshit — Videos In Spring 2017, we taught the course for the first time as a series of ten hour-long lectures. These lectures were recorded using multiple cameras and edited to form a video series. We have divided up every lecture into a set of a shorter segments; each segment should more or less stand alone on its own merits. The full playlist of all course videos is available on the UW Information School's YouTube channel. Lecture 1: An Introduction to Bullshit Iron(III) oxide - Sciencemadness Wiki Iron(III) oxide, often referred to as red iron oxide, is the chemical compound with chemical formula Fe2O3. It is the main component of rust and acts as the oxidizing agent in the classic thermite reaction with aluminium.

Pigment Synthetic ultramarine pigment is chemically identical to natural ultramarine Pigment Colours - Classification A pigment is a material that changes the color of reflected or transmitted light as the result of wavelength-selective absorption. This physical process differs from fluorescence, phosphorescence, and other forms of luminescence, in which a material emits light. Preparing a DVD-R to act as a diffraction grating Main image - A segment of a DVD-R bottom layer with the photo-reactive dye removed See also - Does leaving the dye on a DVD-R grating make any difference? All DVD-Rs are made with two layers of moulded polycarbonate about 0.58mm thick, glued together. There is a guide groove for the burning laser moulded into the upper (inside) surface of the lower layer (the 'label' side being the top side of the DVD-R).

How To Teach a 5 to 10 Year Old To Draw a Person The ‘Obvious’ Is Always Overlooked Take a quick look at your student’s or child’s drawing of a person. Ask the ‘obvious’ questions. “Are all the parts assembled in the ‘right’ place?” Do the arms come out of the shoulders?
