Discover how human activity has led to some of the world’s disasters in How It Works magazine No. 160.Human ingenuity robbed us of us Origin of hunter-gatherers, Simply survive with other species and become an astronaut Orbiting space station While millions of us are watching live Rocket launch Thousands of miles away. We have become masters of our own destiny on Earth, but many times it has been proven to be more than our ability to destroy our planet for ourselves and other creatures. increase. In this issue, we’ll look at how we caused some of the worst disasters in recent history, and how we did the enormous task of clearing up the terrible turmoil we created. increase.
Also, in this issue, discover how radar can detect distant objects far beyond human senses. Learn about stalactites and stalagmites, and the slow but complex chemistry that leads to the fantastic underground pillars of nature that have formed over tens of thousands of years. Recently discovered beliefs about the history of aviation and how humans have learned to fly, revealing the chemistry of the brain behind addiction and the social / environmental factors that cause addiction. Unbelievably new outer planets, and-can we control the weather?

from Nuclear explosion For oil spills, we’ll explain how some of the most harmful man-made disasters in history happened. Disaster cleanup..Including catastrophic ones Deepwater Horizon oil spill: Oil spills are one of the most visible disasters of our time, and the 2010 Deepwater Horizon incident is said to be the largest offshore oil spill in history. The name comes from the drilling rig at the center of the case. Deepwater Horizon’s oil rig was a floating platform for drilling wells for exploration at 5,600 meters below the surface of the Gulf of Mexico. It wasn’t a problem and the rig was working well within that limit. However, on April 20, 2010, methane gas in the water expanded and rose to the drilling rig, where it ignited and exploded.

We will also delve into the tragic history of Libby, Montana. At first it was about a typical American frontier settlement, but in the 1800s pioneers arrived and the town expanded thanks to the construction of mines and railroads. In 1919, the discovery of a mineral called vermiculite changed Libby’s fate. Vermiculite has many uses, from gardening to auto parts, and by 1963 Libby’s mines had produced 80% of the world’s supply.But for some vermiculite asbestos, A dangerous substance that can cause widespread lung problems. Libby’s vermiculite did. The mining company knew about its dangerous side effects, but without telling anyone, the Libby people used mining waste for school projects and construction and landscaping, including ice skating rinks. As a result, nearly 10% of the town’s population suffers from asbestos-related illnesses, and these people were not necessarily miners.

How radar works
Among all the technological advances that have helped Britain and the Allies Win in World War IIYou can’t exaggerate how important radar was in the Battle of Britain. In 1940, an aerial battle was fought over the skies of England. Hitler was planning an invasion, but had to gain an aerial advantage. He attacked London and the Royal Air Force airfields with bombers, sending a series of numerically superior German Air Force waves to Britain. With so many defeated, the RAF will need a miracle to win.And that miracle was called radar..
Radar (short for radio detection and ranging) used radio waves to detect the arrival of German aircraft. From radar towers scattered south and east of the country, the system emits radio waves, continues to move until it bounces off something like an incoming plane, and returns to be picked up by a radar receiver. By calculating the time it took for the waves to return, a skilled operator could know the altitude, range, and direction of the incoming enemy aircraft. This gives the Royal Air Force enough time to scramble its planes to respond to the incoming threats, helping Britain win the battle and hit the Third Reich’s invasion plans. I did.
of How radar works, BAE Systems sensing engineer Henry White, How It Works to How It Works Quantum radar Take detection to a whole new level. “All radars use a clock to measure the time it takes for a wave to hit an object and return to the antenna. A time delay tells you how far the object is. It moves quickly while tracking. If we could make the clock more accurate, we would be able to actually detect the shape of the object and figure out exactly what it was. We are currently researching how to insert a quantum clock into a radar. Is about 1000 times more accurate than the watches we currently use. ”

Can you control the weather?
It may be a small daily story, but the weather and its changing conditions have a huge impact on the planet as a whole.Prolonged lack of rain in some countries Create a harsh and dry condition, While others are constantly threatened Flood surge.. Stormy weather varies widely from country to country, but overall global average temperatures are steadily rising.
of Can you control the weather?, We explore modern technological advances and understanding of meteorological processes, and how scientists are discovering new ways to manipulate weather. Instead of succumbing to the natural schedule, projects are underway to rain the sky, remove carbon dioxide (CO2) from the atmosphere, and prevent extreme weather events such as hurricanes and floods.
Geoengineering is a term used to describe meteorological operations to combat the effects of global warming. These methods generally fall into two categories: carbon dioxide removal and solar geoengineering. The purpose of geoengineering is to protect the earth. But some scientists believe we shouldn’t play with nature. When analyzed theoretically, the results may look positive, but what about the results we are unaware of?
Not all weather control technologies are developed for the planet. We may also work on smaller issues. For example, China is known for using weather correction programs to control weather forecasts for events such as the Olympics. Prior to the 2008 Beijing Olympics, the country carried out artificial rainfall to rain the clouds above the capital, ensuring that it would rain before the event, not during an event like the opening ceremony. did.
