To observe equilbrium and transition to another state, you may need to first measure 1st derivative. Indeed, I imagine it would come up in a lot of places where things can transition between states of equilibrium. (am i right on that, i haven't thought too hard, just whipped it out). Are the rate of defaults (or adverse events) increasing or decreasing: 2nd derivative.

Lets take mortgage stock/book cause it's easy.Ī percentage of mortages go into default. Does that make it a third derivative? Exercise left for the reader :)Ĭlosely related to interest rates and equilibrium funnily enough. And that you can take a derivative on the numbers generated by these individual observations themselves measuring localised 1st/2nd derivatives. You could get really fancy and say that climate is a statistical function on localised individual weather observations which follow the above pattern. as carbon emissions start to enter the atmosphere after the industrial revolution) = 2nd derivative. Is the rate of change increasing or decreasing (i.e. Is it increasing/decreasing = 1st derivative. R0 increasing or decreasing = 2nd derivative.Ĭlimate/phenomenon (i.e. New infection rate, spread, R0 etc = 1st derivative.

Pandemics, disease control, and epidemiology :)

Consumers and regulators start avoiding or banning some of them, let's just spin up some derivatives of the perfluorooctane sulfonic acids that they haven't cracked down on yet and put that in everything until the people become savvy and then we'll move on to newer harmful unbanned things!

US Controlled substances act in 1986 spelled out the number of steps was irrelevant.Īnother area we're seeing twice and third derivatives to get around regulatory & consumer purview is perfluoroalkyl chemicals ie PFOAs, PFAS, PFOS. Another example is making buprenorphine from thebaine which is used for making oxycodone, oxymorphone, buprenorphine, naloxone and other opiate agonists. there are derivatives of derivatives which create (fun, lol) headaches for pharma licensing and marketing regulatory authorities.Įcgonine is a tropane derivative from coca leaves and is convertible 2-carbomethoxytropinone and then cocaine. First-order derivatives are drugs that are created from the parent drug via just one chemical reaction. The best part is there's a stupidly simple approximation to calculate how much bending you get from a single force (Hooke's law ): the distance the beam moves is proportional to the force (by some constant you can get either with these derivative calculations or by experiment).ĭrug derivatives are pretty common in chemistry and pharma. This is often visualized in a 'shear force and bending moment diagram'. If you consider it the other way around, the force is the third derivative of the resulting beam shape. The second integral is the slope of the beam, and the third integral is the actual shape of the bent beam. The first integral of this is the torque ('moment') on each segment. The vertical force on each segment due to the force pressing down is constant over the beam. To calculate this, one considers the beam as a number of little segments connected to one another.

If you hold a thin beam (say, a ruler or a stiff piece of paper) horizontally in the air by one end, and press down on the free end, it bends from a straight line into a third-order (cubic) polynomial. The standard example is simple beam bending. They might be on a nice path for the future if you're thinking very long term, but in general these equity markets are placing the most weight on what's happening in the next 6-24 months, and in the next 6-24 months I can't see a bullish argument for Beyond Meat.Ī fun one with easy visualization is mechanical engineering statics, in which one calculates how much something deforms from a force (e.g., a bookshelf or bridge sags, a spring stretches, or an elastic tire or sponge or pillow squishes). It's exactly the type of business I can see suffering over the next few years as disposable income shrinks.

Even within that growing plant based market, Beyond Meat is expensive. Sure, there is a general growing market for plant based options but it's a slow burner. A lot of meat eaters tried these plant based burgers as a gimmick during the initial hype, few continued to buy it regularly. BM's growth has been poor over the last few years. People with plant based diets don't tend to be huge McD consumers. The McD partnership alone isn't going to put them in profit, nowhere close, not to mention McD are going to be suffering themselves (relatively speaking) over the next few years. It's trading way beyond its revenue and losing lots of money. Because Beyond Meat is overvalued right now.
