After the collapse of Mycenaean civilization, Greece emerged from an “Dark Age”, to become one of the world’s most advanced civilisations. They revolutionised politics, philosophy, music and theater – while becoming masters in military strategy as well. Ancient Greeks were pioneers of democracy and masters of both art and science. Socrates, Plato and Aristotle were…
When asked to name the planet closest to earth in size, most will cite Venus. That is because Venus is the smallest of the rocky planets and passes close by Earth every time it orbits our Sun. But Mercury is actually our closest neighbor in terms of size – continue reading to discover why. Mercury…
At noontime, most of the light reaching our eyes appears blue due to gases in our atmosphere scattering it more widely than violet and red hues do. Reason being, air molecules are smaller than the wavelengths of sunlight and shorter wavelengths scatter more strongly compared to longer ones – known as Rayleigh scattering effect. The…
Spacecraft campers represent the height of luxury camping, reserved only for those with the funds available to buy one. A typical 57-foot trailer may cost close to $300,000. These massive homes on wheels are constructed by a small company which takes great pride in customer service, working closely with clients to design an appropriate floorplan…
At day, the sky appears blue because light is scattered by air molecules; this occurs more with wavelengths of blue light than with any other hues. Tyndall came up with this solution by shining a beam of white light through a tank filled with clear water containing small particles suspended in it. He found that…
Kepler monitors 145,000 Sun-like stars for signs of planets passing in front of them, searching for periodic dips in star brightness that might indicate planet orbital activity around its host star. Astronomers look out for patterns suggesting planet presence by tracking periodic brightness dips that might signal their passage. Kepler had been operating successfully until…
Since scientists started studying Mars, much has been learned about it. Robotic spacecraft have even orbited it and touched down on its surface. Mars is a smaller planet than Earth with lower mass, leading to reduced gravity forces and thus lower gravity forces on this world. Mass Mars, also known as “the Red Planet,” is…
People commonly associate blue with feelings of openness, stability and order – no wonder it has become so popular for corporate logos and apparel! When sunlight strikes the atmosphere, its wavelengths disperse in all directions – more efficiently for shorter wavelengths such as violet and blue which gives the sky its distinctive hue. The Sun…
Flowers don’t just add beauty; they play an integral part of a plant’s life cycle! Flower petals act as pollen carriers to spread pollen grains onto nearby flowers where it fertilizes their ovules, helping plants reproduce. Seeds require water, oxygen, and warmth in order to germinate successfully. Once they’ve begun sprouting they form hard outer…
