The desire to wield power over other people and to get enjoyment from doing so are unpleasant traits. While the structure of complex modern society requires hierarchies that have people in positions in authority over others, the exercise of power often extends well beyond the demands of one’s job and some people seem to actually enjoy having others be submissive to them and belittling and humiliating them.

This crash test video provided by Consumer Reports in which a 2009 model car has a frontal offset collision with a much heavier 1959 model shows how much safer cars are now despite being much lighter.
People on the eastern seaboard of the US are digging themselves out after last week’s major snowstorm. One of the things that I have long been curious about is how people actually measure the amount of snow that falls. Unlike rainfall that is relatively easy to measure, snow is very variable in its water content and winds can cause it to swirl and create drifts and uneven amounts even within a small region.

Have you ever wondered what would happen if you placed a washing machine on a trampoline, put a brick into it, and turned it on? Me neither. But somebody thought it might be a good idea and the video below shows what happens. In general, my distaste of waste and wanton destruction of perfectly good appliances makes me reluctant to endorse this kind of thing. But I have to admit to being fascinated by the video because it made me think about the physics that was driving it.

Given that we now have telescopes that can probe far into the most distant regions of the universe, and are even able to detect the existence of what are known as exoplanets (i.e., planets orbiting stars other than our own Sun), you would think that we would pretty much know everything that exists in our own neighborhood of the solar system.

According to the National Oceanic and Atmospheric Administration, 2015 easily broke the previous record for the warmest year that had been set just the previous year.
During 2015, the average temperature across global land and ocean surfaces was 1.62 Fahrenheit (0.90 Celsius) above the 20th century average,” said the NOAA report.
“This was the highest among all years in the 1880-2015 record.”
Compared to 2014, last year was 0.29 Fahrenheit (0.13 Celsius) warmer, the “largest margin by which the annual global temperature record has been broken.”
The Powerball lottery drawing later this week has an estimated jackpot of $1.4 billion, the largest in US history, easily beating the $656 million Mega Millions prize in 2012. Although I don’t buy lottery tickets, the size of the prize made me wonder about the odds involved and whether it might be worthwhile to pick every single number to guarantee winning.

Winter temperatures finally arrived this week in Cleveland, with daytime highs hovering around the freezing mark. This follows the warmest December on record. The snowfall was the third lowest on record with pretty much no snow at all, just three-tenths of an inch, very much below the average of 14.1 inches.

The World Health Organization declares that Guinea is now free of the disease, two years after it made its appearance there, triggering a global panic. The disease killed over 11,000 people in that country and in Liberia and Sierra Leone. Liberia was declared disease-free in September while Sierra Leone was cleared in November.
