Why is the engine compartment and hood of the McLaren F1 supercar covered in gold?

The legendary supercar McLaren F1 until 2005 held the speed record (386 km / h) among production cars and was sold at a price of $ 1,2 million. The hood of this car is covered with gold foil from the inside. This was done, however, not for luxury, but because gold is one of the best reflectors, protecting carbon fiber car body panels from the heat generated by the engine.

Random interesting fact from the Great Encyclopedia:

Where do mosquitoes go in winter?

In winter, in places where winters are cold enough, you will not see mosquitoes, but they continue to live. Only they live in other forms in which we may not recognize the flying and buzzing insect known to us. Mosquitoes spend the first part of their lives in water and the rest on land and in the air. Their life begins at the moment when the female lays her eggs in a reservoir of stagnant water. Soon, larvae hatch from them, which immediately begin to swim and look for food. Soon the larvae turn into pupae, the pupae, in turn, become adult insects and fly away.

The entire journey from egg to adult takes only nine to fourteen days! But when the winter cold sets in, the eggs and larvae "fall into hibernation." Nothing comes out of them. And females of some species of mosquitoes also fall into a kind of hibernation for the winter. Thus, eggs, larvae, pupae, and adult insects wait out the winter.

An interesting fact is that, although a hot climate is most favorable for these insects, and especially the subtropics, where mosquitoes are a real disaster, they are even more of a disaster in the northern regions of Canada, Alaska and Siberia. This is due to the ability of mosquito eggs to survive the winter in the snow. When the snow melts, the insects begin to hatch in such numbers that cases are told when a person went crazy, bitten by a midge!

Of course, the danger that mosquitoes pose to humans is not only that they bite painfully, but even more so that they transfer diseases from sick people to healthy people. The mosquito sucks out disease-causing microbes along with the blood of a sick person. Then, when a mosquito bites a healthy person, it introduces germs into the body along with its saliva. The mosquito does not need these microbes: what it needs is blood.

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

US Cyber Troops Grow 16.01.2014

The US authorities in 2014 will spend $447 million on the needs of the Cyber Command of the Department of Defense, which is 2,3 times more than $191 million spent in 2013.

The new Cyber Command budget was reported by Nextgov, citing official documents published by the U.S. Budgetary Appropriations Commission.

As the Ministry of Defense explained to Nextgov, the increase in cyber command spending is mainly due to an increase in the staff of the unit. As of March 2013, it included about 830 employees. According to the program adopted by the authorities, by 2016 the staff of the cyber unit is planned to be increased by 2 employees annually.

US cyber troops are engaged in identifying and blocking threats from foreign countries affecting military and industrial computer networks. Among their tasks is protection from hacker attacks of the municipal and social infrastructures of the state.

According to the Department of Homeland Security, in 2012 the number of reports of cyberattacks on US computer networks rose to about 153, or 2011% more than in 42.

At the same time, US spending on cyber defense within the budget of the Department of Homeland Security will increase. $2014 million will be allocated under this item in 792, which is $35,5 million more than in 2013.

Thus, the Pentagon and the US Department of Homeland Security will spend a total of more than $2014 billion on cyber attacks and cyber defense in 1,2, or about 30% more than $948 million in 2013. However, both departmental budgets still need Senate approval.
