Today in History: Humans take to the air! but tethered, 1783 (France)

In 1783, two brothers demonstrated their invention, the hot air balloon, before a crowd of dignitaries in Annonay, France. 
Joseph-Michel and Jacques-Étienne Montgolfier, prosperous paper manufacturers (a high-tech industry at the time), experimented with lighter-than-air devices after observing that heated air directed into a paper or fabric bag made the bag rise. After several successful tests, the brothers decided to publicly demonstrate their invention.
The Montgolfiers built a balloon made of silk and lined with paper that was 33 feet (10 meters) in diameter and launched it — with nobody aboard — from the marketplace in Annonay on June 4, 1783, according to Encyclopedia Britannica. The balloon rose to between 5,200 and 6,600 feet (1,600 to 2,000 m) and stayed aloft for 10 minutes, traveling more than a mile (about 2 kilometers).

First crewed flight

The Montgolfiers' next step was to test a balloon with a person as the passenger. On Oct. 15, 1783, the brothers launched a balloon on a tether with Jean-François Pilâtre de Rozier, a chemistry and physics teacher, aboard. He stayed aloft for almost 4 minutes, according to Encyclopedia Britannica.
About a month later, on Nov. 21, Pilâtre de Rozier and the Marquis d'Arlandes, a French military officer, made the first free ascent in a hot air balloon. The pair flew from the center of Paris to the suburbs, about 5.5 miles (9 km), in 25 minutes. Benjamin Franklin wrote in his journal about witnessing the balloon take off:
"We observed it lift off in the most majestic manner. When it reached around 250 feet [76 m] in altitude, the intrepid voyagers lowered their hats to salute the spectators. We could not help feeling a certain mixture of awe and admiration."
The first human passenger was also the first victim of balloon travel. Nearly two years after this flight, Pilâtre de Rozier died on June 15, 1785, when his balloon, filled with a combination of hydrogen and hot air, exploded during an attempt to fly across the English Channel, according to the Royal Society of Chemistry.

That Uplifting Tweet You Just Shared? A Russian Troll Sent It

Image
Here’s what Russia’s 2020 disinformation operations look like, according to two experts on social media and propaganda. By   DARREN LINVILL   &   PATRICK WARREN Internet trolls don’t troll. Not the professionals at least. Professional trolls don’t go on social media to antagonize liberals or belittle conservatives. They are not narrow minded, drunk or angry. They don’t lack basic English language skills. They certainly aren’t  “somebody sitting on their bed that weighs 400 pounds,”  as the president once put it. Your stereotypical trolls do exist on social media, but the amateurs aren’t a threat to Western democracy. Professional trolls, on the other hand, are the tip of the spear in the new digital, ideological battleground. To combat the threat they pose, we must first understand them — and take them seriously.

The Nightmare Scenario That Keeps Election Lawyers Up At Night -- And Could Hand Trump A Second Term

The Nightmare Scenario That Keeps Election Lawyers Up At Night -- And Could Hand Trump A Second Term   (Photo: Photos: Getty Images) Americans will almost certainly go to bed on Nov. 3 without knowing who won the presidential election. Since millions of people will vote by mail, constraints on time and resources will slow ballot counting into potentially a weeks-long process. Voting patterns suggest it’s likely that President  Donald Trump  could end Election Day in the lead in certain key states, only to be overtaken by Democratic opponent  Joe Biden  when more votes are tallied.  This could create a nightmare scenario during the three months stretching from Election Day to the Jan. 20 inauguration: a battle on the state and congressional level over who is the legitimate winner. This could include Congress reconvening on Jan. 6, presided over by Vice President  Mike Pence , with no consensus over its potential role in choosing the next president. This is arguably the most likely of th

Philosophical Question #14 – Lifestyle Choices

Image
Here is an interesting question in my list of philosophical questions: 1.) Should governments have penalties for those who live unhealthy lifestyles? A list of unhealthy lifestyles would include things like smoking, drinking, illegal drugs, prostitution, and other “vice” type activities. I guess the “government penalties” would be referring to monetary punishments, withholding medical treatments (insurance companies would love that), possibly imposing/regulating very high (exorbitant) prices on things considered unhealthy in order to cut down on their use, and other possibilities. 2.) Or, would you say that living an unhealthy lifestyle, likely resulting in a LOT of eventual personal pain and suffering, should be punishment enough for unhealthy lifestyles? When people make bad choices in life, often in their youth where ignorance and immediate gratification takes them over,  3.) Should a society be obligated to help "fix" them, by way of tax money?   Is that part of
