Today, computer cooling consumes even more power than the hardware itself. Conventional cooling systems are based on fans located on heatsinks (products of high thermal conductivity) that expel the received heat to the outside. These are generally costly, ineffective, and polluting, so researchers are developing alternative methods, notably the flow of water to the heart of the equipment.
58% of Spaniards claim to read between one and two hours a day, more time than they dedicated to this activity 20 years ago, and the majority prefer the paper format over digital, according to a survey carried out recently by the department stores of books and Fnac music.
A healthy way to replace the fluids we lose in summer is to eat fruit with high liquid content. The fruit that contains the most amount of water is strawberry (91.3%), followed by watermelon (91.2%), grapefruit (91%), melon (90%) and peach (88%).
Until today, the most accepted belief was that 4,500 million years ago a gigantic object collided with the Earth and, from the detached fragments, the Moon was born; and that the impact caused such heat that all the hydrogen evaporated and was lost in space, leaving both the Earth and its satellite dry. Later, the water returned to Earth in meteorites and to the Moon in comets.
The widespread myth that you need to drink eight glasses of water a day to prevent dehydration was spawned in the mid-20th century and continues to be very popular today. But the truth is that there is no scientific study to prove it, as Margaret McCarthey pointed out in the British Medical Journal (BMJ).
On average, women dress daily in clothes made with a water consumption of up to 11,000 liters, 3,000 liters less than the amount of garments worn by an adolescent or an adult man. This has been calculated by researchers from the Water Observatory of the Botín Foundation and the Textile Technological Institute (aitex), of Alicante, with the collaboration of several clothing manufacturers.
An international team of scientists has managed to tie knots with water in a laboratory, just a century after the idea was suggested. The feat, which has been published in 'Nature Physics', paves the way for researchers to study the twists and turns that occur in phenomena such as ionized gases in the solar atmosphere, superconducting materials, liquid crystals and quantum fields described by the elementary particles.
Martin Waugh is an American physicist who combines art and science to capture the beauty of raindrops. Using high speed photography and modifying the size, speed and position of the drops, the colo
Danni Büchner is invited to Sam Dylan's Halloween party. But the "Goodbye Germany" emigrant has no desire for many other party guests. And find clear words.
