Another post dedicated to optical illusions, many of us interested in this topic. Optical illusions created our mind, which is like the easiest way to look at things. At first glance, we are try to correlate the images with the most basic and intimate interpretation, and only in few seconds, we understand what is in the picture, and we begin to see the individual parts.

Change of perspective – is another common technique: it manipulates our visual perception, making the object larger, smaller, closer or farther away than it actually is. In short, Lets look…

Free Energy Machines is it True?

Free Energy Machines

Some believe they’ve cracked the secret of free energy forever with no fuel needed. Is it true?

Call them free energy machines, perpetual motion, over-unity machines, or any other name; a tiger remains a tiger no matter what color you paint his stripes. For as long as human beings have needed electricity or any kind of power source, inventive minds have sought in vain for a perfect solution: free energy forever with no fuel needed. Drawings of plans for perpetual motion machines are found throughout history for as long as we’ve had the science of engineering, and they continue to appear today, perhaps more than ever. Today we’re going to look at some of the most famous examples of free energy machines, and address the common public perception that such miracles actually exist.

The reason that no free energy machine can work, or will ever work, should go without saying; but since the claims continue to persist, it bears a mention. A perpetual motion machine would violate the laws of thermodynamics. Strictly speaking, it is unscientific for me to say that no free energy machine will ever work; but the fundamental laws of the universe are established to such a huge degree of certainty that it’s a limb upon which I’m willing to go out. Specifically, the first law of thermodynamics states that the energy of any closed system remains constant. If you take any energy out of it at all — for example, to make a rotor spin — then you must put in at least an equivalent amount of energy. The second law of thermodynamics states that entropy in any isolated system can only increase but not decrease; basically, systems seek thermal equilibrium. This law prohibits any process in which the only result is that heat moves from a region of lower temperature to a region of higher temperature, or where heat is converted purely into work. All free energy concepts are impossible because, by definition, they violate one or both laws.

The most common perpetual motion concept is a magnetic motor, some arrangement of permanent magnets intended to spin a rotor, push a ball around a path, or keep some other component in motion forever. These days they’re usually blended with a powered electric motor, and the inventor claims that once it gets going, its kinetic energy exceeds the electrical energy put into it. An Internet search yields thousands of results for such machines. Many of them show videos of their machines working. So how do we reconcile this: am I saying all these guys are all liars?

Cases of Time Slips

A white Ford pickup pulled up to cattle pasture near Ponca City, Oklahoma, in early Fall 1971, and stopped at a gate. Karl, Mark, and Gordon worked for cattle feed distributor and were sent to this remote area to pick up a feeder. What they found there has kept them silent for 41 years.

“We opened the gate, which was barbed wire with no lock, and entered,” Karl said. “We went on the property, which was covered with grass up to and over the hood of the truck.”

They drove through the tall grass to the tank that sat close to a red barn and got out of the truck.

“We realized the tank was almost half full and too heavy to load,” Karl said. “We decided to leave and drove around the red barn and we saw a large, two story white house, with no lights in front of us.”

The trio drove back to the cattle feed company and the boss said he’d drain the tank and they could pick it up tomorrow.

“We went to the location to retrieve the tank the next night,” Karl said. “This time we decided to go through the old white big house on the hill and brought our shotguns.”

They drove onto the property over the path they’d made through the grass the day before and loaded the tank. Then they pulled around the barn toward the house. What they saw burned into their memories.

“It was no longer there,” Karl said. “We walked up the hill where it stood and there were no signs of demolition, no foundation, nothing at all. What we all seemed to witness the night before was no longer there. We have talked to each other over the years but none of us can begin to explain this vision.”

Did these men witness a slip in time?

Time slips have been reported throughout history. English women vacationing in France in 1901 claimed they stepped into the French Revolution, and two English couples traveling in Spain in the 1970s stayed at an oddly archaic hotel that was simply gone on their return journey.

Physicists like Albert Einstein, Michio Kaku and Stephen Hawking have all said time travel is theoretically possible; our science just can’t achieve it. But what if nature can?

How can parts of Canada be ‘missing’ gravity?

For more than 40 years, scientists have tried to figure out what’s causing large parts of Canada, particularly the Hudson Bay region, to be “missing” gravity. In other words, gravity in the Hudson Bay area and surrounding regions is lower than it is in other parts of the world, a phenomenon first identified in the 1960s when the Earth’s global gravity fields were being charted.

Two theories have been proposed to account for this anomaly. But before we go over them, it’s important to first consider what creates gravity. At a basic level, gravity is proportional to mass. So when the mass of an area is somehow made smaller, gravity is made smaller. Gravity can vary on different parts of the Earth. Although we usually think of it as a ball, the Earth actually bulges at the Equator and gets flatter at the poles due to its rotation. The Earth’s mass is not spread out proportionally, and it can shift position over time. So scientists proposed two theories to explain how the mass of the Hudson Bay area had decreased and contributed to the area’s lower gravity.

According to reports, 21 people had to be treated for burns from walking over hot coals at a Tony Robbins inspirational event.

Robbins is a successful self-help guru with a schtick that depends upon the scientific illiteracy of his audience. After a session of telling people how to “unleash the power within” he demonstrates their new-found power by inviting them to walk barefoot over hot burning coals while thinking about cool moss. This is meant to demonstrate the power of mind over matter. This is, of course, nonsense.

The Hot Coal Deception

Many physicists have used the hot coal demonstration to teach a bit of elementary physics, as there is a very simple explanation for how people can walk over hot coals in their bare feet.
