Stegräknare är super praktiska för att hjälpa oss att övervaka våra träningsvanor, särskilt när vi försöker bli mer aktiva. Och om du använder en app för att räkna steg vet du hur användbara de kan vara för att hålla reda på dina fitnessmål . Men hur exakt är din stegräkningsapp egentligen? Visar stegräknaren i telefonen rätt data? Enligt en studie som publicerades i Journal of Sports Sciences, är din iPhone stegräknare förmodligen inte den bästa som finns, men vad som är bra är att du troligen går fler steg än vad din iphone säger Forskare vid University of British Columbia utvecklade en tvådelad studie - en som genomfördes under laboratorieförhållanden och den andra i en verklig miljö - för att jämföra iPhones hälsp app med en bärbar midjebärd stegräknare byggd enbart för ändamål

Det är lätt att titta på en teknik såsom en högtalare och vara förbryllad över hur de fungerar rent tekniskt. Dess koppling mellan elektricitet och magnetism används oftast genom att skapa en från den andra. Magnetfält kan skapa eller inducera elektriska fält. Fenomenet att inducera ett elektriskt fält från ett magnetfält har gett ett enkelt namn på elektromagnetisk induktion. Runt skruven finns en trådspole, och genom att trycka på knappen kan elektrisk ström från utloppet strömma genom spolarna och den elektriska strömmen inducerar ett magnetfält - skapar en tillfällig magnet ur skruven. Inuti en högtalare hittar du också en typ av elektromagnet med trådspolar lindade runt en permanent magnet. Pulser av elektricitet transporterar ljudinformation från din telefon ner genom

If you really want to make your online business grow. The strategy is only the key to success for content marketing.  Nowadays everyone is thinking about boosting its digital presence via effective digital strategies. And it makes a complete sense if you really want to make your online business grow. The strategy is only the key to success for content marketing. By just putting content online, one could not improve marketing performance, as a documented digital content strategy is a road map that aligns the approach to marketing by following the company’s operational plan. By just adding content with no direction, strategy, purpose, goals and the targeted audience will just end up wasting your time and money, even if your content is incredible! Do you know what it actually

You've probably seen the astronauts floating around in their spacecraft around the Earth. But have you ever wondered why? The answer is that they are in free fall because they are only affected by the gravity of the earth and no other forces. On the other hand, if you stand on the ground it will counteract gravity so that you are in balance and feel a weight. When you use the word weightless, in most cases, you mean that you are in free fall, and not the absence of gravity. The astronauts in orbit around the earth are constantly in free fall at a rate that is adapted so that they do not fall down to the earth, but constantly fall "around" the earth. GRAVITY Gravity (of Latin gravis meaning heavy), or gravity, is one of the four fundamental forces of the universe. It is the attractive ...

What happens if the moon disappears? Or if some planets in the solar system collide and get into space. Will it affect the earth? If the Moon disappears (though we don't know how it could happen) the sky would be darker at night, but otherwise we probably wouldn't notice it as much. After a long time, perhaps the earth's magnetic field would weaken. The planets are in very different orbits far apart, there is no risk that we will see them collide for billions of years. What would happen then depends on exactly what happens. If the earth were to collide with another planet, it would certainly be impossible to live here, but you need not worry about something like that. It is much more dangerous in traffic and it is important that you be careful there.

Exactly 30 years ago, on April 21, 1989, Nintendo released the next generation console for handheld games after the success of their Game & Watch game. It was a gray machine with a green LCD screen and red buttons where the games were loaded via cassettes. It was called Game Boy and would take the world by storm. The concept was mainly Satoru Okada and Gunpei Yokoi, a couple of Nintendo's veterans in the development department. The new handheld console with interchangeable game cartridges quickly became a success. After the release in Japan in 1989, the console reached the United States a few months later, and here in Europe we had to wait more than a year when Game Boy was first released here in 1990. The little gray console got a long life span and was manufactured to change in...

How 3D Printers Work 3D printers have long been huge colossus only adapted for the industry but now they have shrunk and also work for home use. Today, there are models for both true enthusiasts with a great computer experience for more pure amateurs. No matter what level you are at when it comes to how 3D printers work and what knowledge of computers, technology and 3D equipment you possess, there is a 3D printer to suit all different needs. We will go over the basic concepts of 3D printers and help you understand your needs and opportunities a little better. 3D printers were something that felt very distant to ordinary households, and technology has long struggled with the same problems as the first-generation computers: they were simply too big. But as the technology has been ...

At MIT you work on a number of concepts for more efficient windows. Among other things, an aerogel that is lighter than marshmallows and provides 50 percent better insulation than traditional glass panes. According to the US Energy Agency, buildings account for 40 percent of the country's energy consumption. But according to the authority's calculations, about 30 percent of that energy is lost by heat leaking or penetrating through the windows of the properties. Developing window glass with a minimal energy loss is thus an important contribution. At MIT, a team works on several solutions. Among other things, researcher Elise Strobach has spent two years developing "Aeroshield". It is a transparent silica airgel that consists of 95 percent of air. The other five percent are silica nan...
