"The good thing about science is that it's true whether or not you believe in it" Neil deGrasse Tyson

To calculate the volume of a cone with calculus, use the disk method, which involves summing up the volumes of infinitesimally thin disks from the base to the apex. First, set up the integral using the equation for the radius \(y\) of each disk at a given height \(x\). For a cone with radius \(r\) and height \(h\), the radius of a disk at height \(x\) is \(y=\frac{r}{h}x\). The volume is then found by integrating the area of these disks, \(A(x)=\pi y^{2}\), from the base (\(x=0\)) to the top (\(x=h\)), which gives the formula \(V=\int _{0}^{h}\pi (\frac{r}{h}x)^{2}dx\).

My mother taught physics, chemistry and mathematics in high school in Buenos Aires and in Mexico City until she moved to Nueva Rosita, Coahuila where she taught the whole curriculum to the 6^th, 7^th and 8^th grades in a one room schoolhouse. I was one of six boys in the 8^th grade.

In 1962 I learned integral and differential calculus and my world was never the same again. My Eureka moment happened when I learned two ways of calculating the volume of a cone. In the second method, not illustrated here, you rotate a triangle (from the base of the cone to the tip) 360 degrees.

All the above is to cement that I trust science but opt for using the words chemistry and physics as science now is a word as empty of meaning as iconic and clinically proven.

In the late 40 and 50 in Buenos Aires, I feared a particular vaccine. It was the one for diphtheria. What was unique about this vaccine is that it was administered on the spinal column. Since then I have been terrified of hypodermic needles, and not too long ago, I fainted when I went for a blood test and saw the blood being taken out.

This does not mean that I do not believe in vaccination. I am getting both the latest covid and influenza vaccines in a few days.

When I was learning the calculus my chemistry book was authored by Linus Pauling. Perhaps because I admired the man and I have been taking 2000 mg of Vitamin C every morning since covid began I have been free of the disease.

I have a first cousin who lives in Florida that used to send me covid vaccine conspiracy theory email plus would tell me that covid was a bad cold. I did not have the heart to tell him that I have a friend in Barcelona who has suffered an almost five-year long covid.

Yes I “believe” in science.
