    Fortran Passing variables in FORTRAN

    In FORTRAN, list directed writes and reads are a convenient way to pass data in a formatted file that can be easily read by a programmer or another FORTRAN program. That can really help in debugging. (See List-Directed I/O)

    B Large Scale Data Collection

    I think that your result makes sense. Suppose that each week, the errors remaining that week are a certain proportion of the remaining errors from the prior week. That is a reasonable assumption to make for your problem. The errors are the deaths that week which were not included in the death...

    Or write a top level script that parses outputs from one program and calls another with data on the command line.

    Other Advice for a middle schooler interested in majoring in CS

    There are some Youtube tutorials that teach programming AI image recognition using Python. IMO, they are a very good way to start self-teaching the subject. Here is a series that uses the Jetson Nano, which is a single-board-computer with some special hardware for neural networks: Learning...

    B Help answer student question about infinity?

    Yes, you are. Any rational number, say 99/1000, will eventually be gotten to. The counting will wind around until it finally reaches up to the 1000th row and will start to include that row, starting with 1/1000. from then on, the counting will keep coming back up to that row (and beyond) and...

    B Help answer student question about infinity?

    Regarding counting the rational numbers. This explains how to count the rational numbers: Integers & Rationals are both infinite but is it the SAME infinity?

    B Help answer student question about infinity?

    Sure, IMO, a line with no width is easy to imagine. Good question. The phrase in mathematics does not mean finite and countable. The rational numbers can be matched up one-to-one with the counting numbers, 1,2,3,... to infinity. That is called "countably infinite". On the other hand, there are...

    B Clever Geometry in this Video

    Now I feel like a caveman confused by fire. A lot of the animated Youtube videos have fooled me recently. They have become incredibly realistic. This one is clearly identified as animated using Blender in the Youtube description. I wish that Youtube had a policy that the title indicate CGI.

    B Help answer student question about infinity?

    That is a question that is discussed here and elsewhere occasionally. It is not a simple question. I personally have no problem with saying that a number between 0 and 1 has been selected using a uniform distribution, even though there are uncountably infinite numbers there, each with a zero...

    B Clever Geometry in this Video

    I'm not as impressed by how they are moving now as I am that the balls were initially set up perfectly.

    B Large Scale Data Collection

    Determining the "ultimate correct value" may be asking too much. When data is being recorded, there are delays and several errors that are made. Some are found and corrected. Others are not. I do not know if the CDC ever corrects whatever data source you are using. Do they only accept revised...

    Other What's the point of a thesis?

    Yes. But I did my thesis in the old days when a person who lied on a published paper was thrown into the T-rex cage to be eaten. ;-)

    NHST statistics for % of students late to class

    This presents a question. When testing the alternative hypotheses, do you use the parameters of the null hypothesis or of the alternative hypothesis? Is the goal to see if the alternative hypothesis, using its parameters, is possible/likely or to show that the null hypothesis, using its...

    NHST statistics for % of students late to class

    The null hypothesis is the one that will be assumed unless the data indicates otherwise. I would chose the option with the least risk and disturbance as the null hypothesis. This problem statement does not it clear to me which should be the null hypothesis, but, with no other information, I...

    B Help answer student question about infinity?

    He can start anywhere on the rope and move along it. He can always find the knot in finite time because he is a finite distance from the knot.
