We Showed 'Troll Physics' Comics to a Physics Professor. Here's His Reaction. Is it possible to "troll" the very laws of matter and motion that govern the universe for your own kinetic benefit? For example, can one survive a falling elevator by jumping up in the air at the last minute? Also, f*cking electromagnetism - how does it work? If you've pondered any of those questions before, the blog Troll Physics offers incredibly simple but impossible "hacks" for manipulating the laws of nature to yield infinite energy, money and/or sexual partners. Since this site is pretty much a physics teacher's worst nightmare, I cornered one to get his reaction. DM: "Up" is not "North"...the only reasonable meaning for the word "up" is "in the opposite direction of the Earth's gravitational pull at the surface." DM: Jumping off the ground - or even a chair on the ground - is nothing like jumping off a chair while you and the chair are in freefall. DM: One look at the bottoms of the two wheels is enough to see that this doesn't amount to "downhill" in any way whatsoever.

34 Lost Cities Forgotten by Time It’s hard to imagine how an entire city can get lost but that’s exactly what has happened to the lost cities on this list. There are actually many reasons why a city has to be abandoned. War, natural disasters, climate change and the loss of important trading partners to name a few. Whatever the cause, these lost cities were forgotten in time until they were rediscovered centuries later. 34Carthage Located in present-day Tunisia, Carthage was founded by Phoenician colonists and became a major power in the Mediterranean.

Bamboo Machine Setting up the "symbiosis" machine in the botanical garden´s tropical greenhouse. The "simbiosis" machine was built for the exhibition "Natürlich" (natural) that was shown in the public greenhouses of Hamburg´s botanical garden in 2009. I was always fascinated by the immense forces hidden in nature like small shoots cracking massive concrete and roots lifting up sidewalks. While looking for a way to make these slow but powerful processes perceptible I read about the growth rate of bamboo: In the tropics it grows up to 1.5 meters a day while having it´s final diameter right from the beginning. By limiting the machine´s functions to pumping water towards the bamboo the "symbiosis" also suggests a beneficial coexistence of nature and machines: We could try to find more sensitive ways to harvest the energy that is already there instead of just cutting plants down and burning them as fuel. Illuatration of the machine´s working principle.
31 Quotes That Will Give You Chills I think quotes have a powerful way of conveying an attitude to you which sometimes resonates so much that you feel ‘chills’ inside. Here’s a list of the quotes which have given me the most of these “chills”. Enjoy! Some people die at 25 and aren’t buried until 75. What's In a Face? Several years ago, a woman named Brook White appeared on the reality TV competition show . White was 24 years old, blond, and strikingly pretty. When she sang her song, "Like a Star," she struck a familiar chord among some viewers. White said nothing about her religion , but Mormons, members of the Church of Jesus Christ of Latter Day Saints, were certain that she was one of their own. "She has the Mormon Glow," one blogger wrote, referring to the belief that the faithful radiate the Holy Spirit. White mentioned that she never drank a cup of coffee or watched an R-rated movie—signs of a Mormon-like squeaky-clean lifestyle. Soon after, psychologists Nalini Ambady, then at Tufts University, and Nicholas Rule, at the University of Toronto, set out to test the Mormon glow. They certainly could—and in just a glance. To determine what exactly triggers Mordar, Ambady and Rule cropped photos beyond recognition. Mormons don't drink or smoke. BEYOND THE HALO EFFECT: Attractiveness and Personality
How Lock Picking Works" Most people carry five to 10 keys with them whenever they go out. On your key ring you might have several keys for the house, one or two more for the car and a few for the office or a friend's house. Your key ring is a clear demonstration of just how ubiquitous lock technology is: You probably interact with locks dozens of times every week. The main reason we use locks everywhere is that they provide us with a sense of security. In this article, we'll look at the very real practice of lock picking, exploring the fascinating technology of locks and keys in the process. Locksmiths define lock-picking as the manipulation of a lock's components to open a lock without a key. Locks come in all shapes and sizes, with many innovative design variations. For most of us, the most familiar lock is the standard dead-bolt lock you might find on a front door. A deadbolt lock's only job is to make it simple for someone with a key to move the bolt but difficult for someone without a key to move it.
