As we saw in the previous entry of this series, skepticism had a relatively minor role during the development of medieval philosophy, with the main exception of the interesting possibility of interpreting the Pseudo-Dionysius as a skeptic about our knowledge of the nature of God (not, of course, of its being… save for ‘being’ being […]

New mathematical definition may help identify chaos A new mathematical definition looks to describe the potential for chaos. The theory is roughly based on something akin to entropy, the degree of randomness within a system. “You could say you have chaos if you have exponential growth of uncertainty. That could happen in relatively simple systems […]

We are all familiar with the equation of ideal gases: PV = nRT. To deduce this equation, an ideal model of the gas is considered. In this model, gases are composed of particles so tiny compared to the volume of the gas that they can be considered zero-volume points in space, and there are no […]

Laziness, sloth or indolence is, depending on who you ask, a sin, a psychological characteristic, or a basic human right. It is usually used as a pejorative and is considered a disinclination, a personal choice where one  the lazy person  decides not to carry out an activity despite having the ability, the time […]

Scientists in Antarctica find evidence of neutrinos’ existence The existence of cosmic neutrinos has been confirmed by scientists at the IceCube Neutrino Observatory in Antarctica. Researchers combed through years of data collected by sensors buried in the ice and pinpointed 21 ultra high-energy muons created by rare neutrino interactions with other particles. They say the […]

¨The chemical bond¨ is one of the most often used concepts in chemistry. It is also one of the eldest terms since the first definition of chemical bond comes from the studies of G.N. Lewis who published his classical paper on interactions between atoms in 1916 . Lewis stated that ¨ we shall say that […]

One of the first things that we are taught in school is that living things are born, grow, reproduce and die. We can think of aging as the line that connects these events, lifespan as the length of that line and senescence as the step that goes from reproducing to dying. The three terms bring […]

Small Jupiter-like exoplanet viewed directly by Earth-based telescope An exoplanet resembling a young Jupiter has been found by astronomers using an Earth-based telescope, the Gemini Planet Imager in Chile, according to findings published online in Science. The gas giant has been dubbed 51 Eridani b and is about 96 light-years from Earth. “To detect planets […]

Minimizing losses in any kind of electronic device is always important, but it is paramount in nanoelectronics. Still, most of the phenomena that lead to inefficiencies in the operation of these nanodevices are poorly understood. Consider the case of quantum dots. A quantum dot is a nanometric crystalline structure of semiconductor materials. In a quantum […]

You come back home really tired after a long day at work and you decide to take that loooong bath you’ve been waiting for. You stay in the water for some time and suddenly you realize your fingers are wrinkling. Oh boy, that is telling you that you’ve been there for a while and reminds […]
