It’s a very common misconception, but in fact the ozone hole does not extend over Australia. Ozone depleting substances have resulted in a thinning of ozone above Australia of about five per cent, whereas over Antarctica in spring almost complete loss of ozone is seen in some layers. Why isRead More →
A hand-dug well may look like the nursery rhyme well in Jack and Jill—a deep hole surrounded by a stone wall. Most wells however, appear as a pipe, usually 5 to 25 centimeters (2 to 10 inches) in diameter, sticking up a short distance above the ground, typically less thanRead More →

Converting the energy of 1,100 decibels to mass yields 1.113×1080 kg, meaning that the radius of the resulting black hole’s event horizon would exceed the diameter of the known universe. Voila! How loud can humans scream? Loud appliances such as a vacuum cleaner or power tools could exceed 80 dB.Read More →
Once you’ve arrived at Rainbow Lake, take some time to explore the area around the dam. … In the summer, locals will swim in this area, and even jump off the dam (guilty). If you choose to swim, or partake in more risky activities around this area, please check theRead More →
As a black hole radiates, its mass decreases, and it starts emitting more and more radiation, causing it to evaporate more and more rapidly. Eventually, it shrinks to around the Planck mass, the point at which its DeBroglie wavelength is equal to the Schwarzschild radius. Do black holes evaporate orRead More →
At its founding in 1930, the Woods Hole Oceanographic Institution joined a thriving ocean science community in the village of Woods Hole, Massachusetts, that included the Marine Biological Laboratory and the National Marine Fisheries Service.
