Scientific method employed on the moon

Before Galileo, and ever since Aristotle, many people believed that heavier objects fell faster than lighter objects. That might be true where air impedes light objects, such as feathers, but many people believed that even in the absence of air heavier objects always fell faster, and it was commonly assumed that, heavier cannonballs fall faster than light cannonballs, even in the absence of any scientific data. The beauty of the scientific method comes front and center in this simple experiment conducted on the surface of the moon by Apollo 15 astronaut Dave Scott.

Your body as an incorrigible servant

Mind over matter, right? When your body aches and begs to stop running, you tell it to keep moving. When your body wants to go to sleep, you exert the will to make it to stay awake, or you make its arms pour coffee into its mouth. We make our bodies drive our cars to work lest those utility bills don’t get paid and “We” will suffer the consequences. Nietzsche began Chapter V of the Gay Science with the following quote as an illustration of his own conception of fearlessness (attributed to Henri de la Tour d’Auvergne, Vicomte de Turenne (1611-75) a great French general):

Sometimes during a battle he could not help trembling. Then he talked to his body as one talks to a servant. He said to it: “You tremble, carcass; but if you knew where I am taking you right now, you would tremble a lot more.”
“We” are in charge, right? Except when we are not. I can think of no better example than when we are nauseated, and our body dramatically takes over, the reverse peristalsis hurling out the offending food, dominating even our minds, until it’s over. Only then can “we” take over again. Consider food traveling in the other direction, too. So many of us tell our bodies to stop eating, yet our bodies keep eating. Day after day. We remind it to look in the mirror and we tell it about our tighter-fitting clothes, yet our bodies don’t care.

Eagle days on the Mississippi River

Although St. Louis was founded as a fur trading post, it is no longer well known as a place to view wildlife. But you can still spot wildlife. Yesterday my family traveled about 10 miles north of downtown St. Louis to the "Old Chain of Rocks Bridge," which spans the Mississippi River.

The bridge was for a time the route used by U.S. Route 66 to cross over the Mississippi. Its most notable feature is a 22-degree bend occurring at the middle of the crossing, necessary to allow river traffic to have uninterrupted navigation on the river. Originally a motor route, the bridge now carries walking and biking trails over the river. The bridge was added to the National Register of Historic Places in 2006.

I do need to add that this was a brilliant use of an old narrow bridge. Click on the thumbnail for a panorama showing the view south from the bridge (Downtown St. Louis is on the horizon to the left). The bridge is located in a big wide relatively quiet area (except for one other bridge that runs parallel), where one can enjoy the Mississippi River and the surrounding undeveloped areas, just north of the Chain of Rocks rapids and a bit south of the confluence between the Missouri and Mississippi Rivers. For one weekend each year, this wonderful bridge is featured as the venue for Eagle Days, a prime spot for viewing American bald Eagles. This is rather cool, to be able to spot wild bald eagles right in the heart of the Midwest. Here's a bit more description of their migration relevant to the Mississippi. [More . . . ]
