Kristi here. I live in Atlanta, Georgia, unofficially and unaffectionately nicknamed Hotlanta. We have two seasons here, winter and summer. Maybe a week of spring or fall thrown in just to make you hope.

While we are accustomed to hot summers, this year it’s been worse than normal. For most of the United States, higher than normal temperatures have been an issue. With the mixed blessing of weather forecasting we can know that this heat isn’t going anywhere anytime soon.

With this expansive summer heat comes the ever present summer rain shower. I have an app on my phone that can tell me whether or not I can expect rain on a given day and what time it’s going to appear, almost down to the minute.

People in the Regency didn’t have the blessing of their local Channel 5 meteorologist or the Weather Channel app on their smart phone. That doesn’t mean that they were unable to make educated forecasts about the day’s weather.

By the time of the Regency, barometers had become a fairly common tool for the upper and middle class. Barometers use a tube filled with liquid to measure the pressure of the atmosphere. Low pressure meant a higher likelihood of rain and clouds whereas high pressure was usually an indicator of clear sunshine.

Weather forecasting is a notoriously fickle thing. Even the best equipped meteorologist today gets the extended forecast wrong most of the time. This was no different for the amateur forecaster in England. The barometric pressure had an average range of 3 inches. As the tools became used by more and more people, adjustments were made to the barometer’s design that made it easier to read the small variations in pressure.

Designers and furniture makers also got into the barometer business, making the tools into decorative pieces for the home and adding thermometers, clocks, or a hygrometer.

The hygrometer used an oat fiber to indicate the humidity in the air.

Barometer makers also created a new way to read the level, creating a wheel gauge that would allow people to more easily detect the level of the mercury. The wheel had a needle that pointed to the pressure level. It had a tendency to stick requiring people to tap lightly on the glass to attain an accurate reading.

While I’m very grateful for the accuracy of Doppler radar and I wouldn’t trade the ability to know how my beach weekend is going to look, I like that so many people acquired a basic knowledge of atmospheric science in order to make their own predictions about the weather.

What is your favorite scientific tool that is now or once was part of everyday life?

For a good portion of the Regency Era (and for the last decade of the 18th Century), England and France found themselves at war.

Again.

War was hardly a new thing for either country. With past wars between England and France, greed, land acquisition, and strengthening the monarchy were the usual catalysts and goals. But with the advent of the French Revolution (and the American Revolution preceding it), a new mentality regarding war arose among the common people.

Before the American and French Revolutions, commoners fought in wars that served to benefit the aristocracy or monarchy. With these new revolutions, regular citizens and common people had a better reason to fight: themselves. Each man standing in France’s army believed he would have a better life if he was allowed to choose who governed his country, rather than be subject to a hereditary monarch.

One thing that the British initially failed to understand about the French  and Americans was WHY they wanted to fight. If you study the French Revolution, American Revolution, Napoleonic War and then the War of 1812, you’ll find this misunderstanding for every single war. With the changes in the French and American governments came a type of energy and belief that the mass of the population could fight for freedom, or for a government they wanted rather than one handed to them by a monarch. And Britain failed to grasp these ideals.

If you were to ask a Frenchman in 1793 and 1803 why he fought, he would have given an answer that involved something about freedom and thwarting tyranny. Even if you were to ask this question a decade later in 1813, after twenty years of war, the answer may well have been the same. “We want freedom. We don’t want another Bourbon king.”

Interestingly enough, if you were to ask a British subject in 1793 why he fought, he likely would have answered “because the king wants us to fight.” If you were to ask the same British soldier that question in 1803, his answer might well be the same, or he might say something to the effect of “because I don’t trust that French Consulate and Napoleon.” If you were to ask the same question again in 1813, the answer would likely be, “Because that Corsican Monster Napoleon is trying to take over Europe, and he’ll take England if we don’t stop him.”

For the first decade of war between France and England, the average British sailor and soldier didn’t have a reason to fight beyond “the government wants us to.” The average Englishman had nothing to gain by fighting with France until the English populace began to believe Napoleon Bonaparte a threat to England (part of which was came about as a result of printing intentionally untrue propaganda against Napoleon). And only then did Britain truly begin to best France in battle.

Now I’m curious about your views. Do you think Britain misunderstood the motivation of both the French and American people when they went to war? Do you think some of that misunderstanding is what led to two decades of war between Britain and France, and the United States defeating Britain two different times?  When you look at the French Revolution and Napoleonic War, do you believe the French people had a reason to fight? Do you believe the British people had a reason to fight?
