Are perpetual motion machines possible?

A wheel that spins forever; a bird that never quenches its thirst; a clock that never stops ticking, an endless source of free energy. These are but the dreams of inventors striving to make perpetual motion machines, machines that can work forever without any energy input. Are these machines possible without violating the laws of physics? No. ‪http://physicsgirl.org/ ‪http://twitter.com/thephysisgirl ‪http://facebook.com/thephysicsgirl ‪http://instagram.com/thephysicsgirl Help us translate our videos! http://www.youtube.com/timedtext_cs_panel?c=UC7DdEm33SyaTDtWYGO2CwdA&tab=2 Unbalanced wheel designed, laser cut and assembled by engineer Kyle Kitzmiller - kylekitzmiller.com Writer: Sophia Chen Editors: Jabril Ashe and Dianna Cowern Host: Dianna Cowern Weather footage: NASA Goddard Zimara’s Windmill drawing: Burton Lee Potterveld Cox’s Timepiece drawing - Mr. Cox’s Perpetual Motion,...

Why Hawaii's volcano is so UNUSUAL

Hawaii is known for its volcanoes, but most volcanoes on earth exist along tectonic plate lines. Hawaii does not! What causes Hawaii to form, and how is it related to the mystery of a magnetic bar code across the Pacific Ocean? Host Dianna Cowern chatted with geologist Noah Randolph-Flagg from UC Berkeley while hiking on the island of Kauai.

200,000 Year Old Ancient Levitation Technology That Defies the Laws of Physics

Unfortunately, science has still not been able to figure out how to levitate larger heavier objects. Yet, history suggests the Ancient Civilizations might have already cracked this secret in their building of the pyramids and other megalithic monuments. Did they have some advanced form of sound levitation to move thousand ton stones—a task that present day builders admit would be difficult even with the use of modern cranes? In many parts of the world there are enormous monoliths that even in this brilliant era of technology no advanced crane could possible raise. Our modern society is proud of its technological and...

There are apparently no shadows in these images. But they were taken during the brightest part of the day. This episode is brought to you by Squarespace: http://www.squarespace.com/physicsgirl There are only certain parts of the year and certain times of day when you can experience the subsolar point or Lahaina noon. There appears to be no shadow because the sun is directly overhead. This phenomenon happens twice a year for latitudes between the tropic of cancer and the tropic of capricorn at solar noon, when the sun is highest in the sky. But you have to be in the right place at...

Why Do Venomous Animals Live In Warm Climates?

Subscribe to Veritasium - it's free! http://bit.ly/YSWpWm As a Canadian-Australian, I have always wondered why it is that Australia has so many venomous animals that can kill you while Canada has virtually none. But it's not just Australia - it seems like all beautiful, warm places are cursed with venomous native species. So I set out to find the truth: why have all these venomous species evolved in the world's best holiday destinations? I asked chemists, visited the zoo, interviewed entomologists and snake experts. The answer I found was complicated: 1. The majority of venomous species are ectotherms, cold-blooded creatures whose internal temperatures...

So I put my own psyche on the line, subjecting myself to over an hour of the most intense quiet...

Lesson 34 - Resonance - Forced Vibrations - Demonstrations in Physics

Demonstrations in Physics was an educational science series produced in Australia by ABC Television in 1969. The series was hosted by American scientist Julius Sumner Miller, who demonstrated experiments involving various disciplines in the world of physics. The series was also released in the United States under the title Science Demonstrations. This program was a series of 45 15 (or so) minute shows on various topics in physics, organized into 3 units: Mechanics, Heat and Temperature/Toys, and Waves and Sound/Electricity and Magnetism.
