Extreme creation of nature

The laws of physics are inexorable and all living creatures of the planet with them should be considered, but in the world there are animals that are "challenged" the axioms of modern science.

Hummingbird Anna

Hummingbirds, despite its small size, is able to accelerate to a speed of 80 km / h. Ford Fiesta can reach speeds twice, but its dimensions are 4 meters. What if we measure the speed, relative to their size? Then Ford would be "flying" would be at a speed of 2092 km / h, twice the speed of sound.

Look at the image below. On it shows the speed of the object relative to their size. Let's start from the bottom. Fighter moves at a speed of 150 lengths in his second peregrine falcon - 200 body lengths per second, the American shuttle - 207 Swallow - 350, and hummingbirds - 383. "efficiency" velocity relative to the size of hummingbirds have significantly higher than that of the shuttle. It turns out that nature has created more sophisticated aircraft, what man created. To move such a rate Hummingbird should do 1000 strokes per minute and wings burned "fuel" as nectar 400 times faster than humans. If we absorb this amount of food, it's probably just burned.



The extremely-thermophilic bacteria

US researchers Freese and Brock have identified a group of bacteria that can live in hot springs, the water temperature reaches 100 ° C. Relatively recently in Hot Springs (California) scientists have discovered species of bacteria that live in underground sources, which is significantly higher than the atmospheric pressure and the water temperature exceeds 100 ° C. How can withstand a temperature of living organisms, because most proteins denaturation temperature of 50-60 ° C (for the human body is the critical temperature of 42 ° C)? It remains a mystery to science.



Deeper and deeper

Record diving owned by the French diver Pascal Bernabe. He reached a depth of 330 meters. At this depth a diver under pressure more than 10 times greater than atmospheric pressure. Very tangible figure, especially when you consider that at a depth of 1 meter of the human body is experiencing additional pressure of 300 kilograms. Considerable pressure at the depth of course fails to neutralize, by supplying breathing gas under high pressure, but the chest wall will continue to experience strong compression. Dive to a depth of 330 meters from the French diver took 10 minutes, while the ascent took 9:00 to avoid the terrible consequences of decompression sickness (With rapid ascent, gases, breathing gas, dissolved in the blood and tissues, forming bubbles that damage blood vessels and paralyze the work of the bodies). To secure the ascent took a brave diver "drag" on itself 7 bottles with breathing gas. In establishing a new record of the French diver to help the team of 30 people.

Perfect combat submarine capable of diving to a depth of 600 meters, where the water pressure is 60 times greater than atmospheric pressure. The depth of 1000 meters they will not reach. At that depth, every centimeter of surface is under pressure liquid column weighing 100 kilograms.

The laws of physics "harsh", but they may seem at first glance, the "retreat" to our brothers mammalian sperm whales. These animals, which are before the dives, as well as we retain in their lungs air, capable of diving to a depth of more than two kilometers and there is about one and half hours. Flexible ribs and structural features of the circulatory system helps sperm whales withstand high pressures and low temperatures.



On a planet many animals which show a phenomenal ability to survive in the most adverse conditions. Take even the penguins of Antarctica, are capable of withstanding temperatures fall below -50 ° C.



Low temperatures are dangerous to all living things. Body fluids (blood, lymph, water), freezing to form ice crystals, which damage cells of capillaries, blood vessels and organs, but many fish are "uneasy." It freezes into ice and then thawed easily, without any harm to their health.

Above listed "animals, extreme" is not the only ones in the world so many amazing organisms, the existence of which would seem to contradict the laws of physics. The ability of living matter by using gimmicks to overcome the limit beyond which life is impossible, is truly amazing.
