I think everybody should know what it's currently going on in #Mexico.
This Sunday morning, federal forces have killed drug cartel boss Nemesio Oseguera a.k.a. "El Mencho". Federal authorities state that this has been done in cooperation with USA agencies.
As a result, violence has erupted in several parts of the country, in what seem retaliation by organized crime. This includes setting fire public transportation and particular vehicles as well as convenience stores and blockade of highways.

OK. According to Wikipedia, the equation for a Bernoulli's lemniscate in the general case is
(𝑥²+𝑦²)² = a²(𝑥²−𝑦²).
So, is the parameter a the analogue of a radius? In other words, is the perimeter of a non-unit lemniscate equal to 2ϖa?

I really don't understand this: "Just as the perimeter of a circle is 2π, the perimeter of this curve is 2ϖ".
Well, technically, the perimeter of a circle is 2π time its radius, so I expect the lemniscate's perimeter is 2ϖ times "some radius". What is it? On a circle it's obvious but not on an 8-shaped curve.

According to this paper, a lot of hot spots are emerging all over the world: zones suffering persistent heatwaves that cannot be predicted by current climate models. #GlobalWarming #ClimateChange #HeatWave #AtmosphericScience

I don't want to be pessimistic, but this looks like it's going to be #HurricaneOtis 2.0.
