What we show with this experiment is that from the moment we receive the information through our senses until we react to it, a few tenths of a second pass: just enough for the brain to process the information from outside, send the pertinent orders to our extremities and they act in consequence.
If we fill a glass with water to the brim and carefully place a needle on its surface, we will verify that, miraculously, it does not sink. The truth is that it is not a miracle but a diaphanous example of what in physics is known as surface tension, which makes the water form drops and does not spread. And it is that the water is wet, but not much.
Experiments carried out by American researchers at the Tevatron suggest that there are up to five versions of the so-called 'God particle' or 'Higgs boson' in the Universe, an element that could solve key questions about the origin of the Universe.
No. The external color of a vehicle does not affect the amount of heat it accumulates in the sun, as Sanford Klein of the Solar Energy Laboratory at the University of Wisconsin Madison found last year.
Can silver cutlery be cleaned in an artisan way? On this there are a large number of remedies, most of them useless. But there are two effective ways to do it. The first is to use hydrogen peroxide. If we have plated cutlery we can use a bucket lined with aluminum foil.
The songs of Let it rain, let it rain ?, the ritual dances to attract the rain, or the "weddings between frogs" that are celebrated in India to "call" the water of the sky in times of drought will fall into oblivion thanks to a successful experiment carried out in Berlin (Germany) that makes it possible to make rain using laser beams.
Does your voice sound better when you sing a song in the shower? The key is in physics. The hard, smooth bathroom walls make this room act as a sounding board, so that sound waves are reflected off the walls, increasing the intensity of the sound and making our voice seem much more powerful.
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.
