Your college year has just started, but you already question yourself about how to do all that creepy stuff in math, programming, biology, management or whatever? Well, sad news but with every passing day there comes even more homework. So how to deal with it? Should every task be done or you can lay back and forget about some of them? Let’s see. (more…)
Antibiotics are complex chemical compounds that destroy pathogenic microbes causing dangerous diseases. Penicillin was first discovered antibacterial drug widely used in medicine. Scientists have discovered hundreds of different antibiotics after penicillin, but evolution is an active process: microbes have developed a possibility to destroy antibiotics causing serious problems in treatment. How did penicillin save millions of people? Did it really become a trigger for the evolution of microbes? (more…)
Gambling was the main reason for the emergence and development of the probability theory. Like any other mathematical theory, it sets its own laws. It seems strange indeed that any case may be regulated. Consequently, knowing the rules, can we win a random game? Let’s see. (more…)
Our life depends on the digital information in all its forms: text, video, audio, photo. Its amount increases with every passing day, so data storage devices with bigger capacity, density and long term of use are of great demand. However, it is challenging to store digital information more than 50 years. Yet, scientists have found relatively stable and compact information storage device – it is… (drum roll) DNA! Its properties are ideal for long-term data storing. So, can DNA molecule store your favorite films is HD quality? How long can the information be stored there? Let’s find out. (more…)
Hey, the great day is coming and the studying is about to start. Don’t worry about the summer now (you’ll have more of them later), worry about your first day at college. Or, probably, you better should not because everyone around you is also worried. You must have heard a lot of advices on how not to fail that, so let’s summarize them and add more useful tips to get lucky. (more…)
Electromagnetic waves that carry the radio signal move with the giant speed – the speed of light, which equals to 300 000 km/s. Here, on Earth we almost don’t feel the delay in the radio signals transfer. But while the reply from the Moon will come to us in half a second, the other one from the Mars takes about six minutes. Moreover, when the distance from the transmitter increases, the radio signal decays rapidly. So, what can we do with this? Fortunately, it is rather difficult but still solvable. (more…)
Summer is, unfortunately, almost over but it’s high time you thought about the prospectives the new studying year can bring. Don’t get mad or anxious with the idea that you know nothing about the place, where you gonna stay for the next several years, there’s no point in it as there are lots of freshmen same as you. The things you may want to know are what else is necessary to do and what to start with. (more…)
