Is Education Research "Claptrap"?
|
| |
Based on my experiences, "claptrap" would also be a suitable
description for much of education research, in particular for research
in mathematics education.
The fate of Naomi Schaefer Riley has been covered in many
publications, including:

Secret math
|
| |
I think it's odd that people can't get patents for math formulas.
I guess if someone invented a new formula they'd probably want to keep it a trade secret.
There must be a lot of secret math out there.
Not good for science.
But science isn't everything.

How do you efficiently sieve for prime 3/4-tuples?
10*(23*63)^2 +/- 1 Mersenne p expon. 1580187223 divides b^bn+3 prime
triple.
I try to promise. my discovery.

Hey folks,
after finding a record prime quadruple, I'd like to stay in the field
of triples and quadruples a bit longer. But the sieving takes a lot of... more »

Create an x-axis based on number of occurences
|
| |
I have a list of prices for condos.
Instead of having an x-axis with an typical increment of $25K I'd like to have a scale that reflects the number of condos that have a particular price.
For instance if most of the condos are between 200K and 400K I might have a scale like:
<=100K 200K 225K 250K 275k >=300K... more »

Charter offers some pretty sweet bandwidth speeds, but get very stingy
when you use them. I am told that all speeds have a 100GB monthly
limit except the last package. With the last package you get 250GB

Anyone care to figure out what percent of the month you are actually... more »

Now by emitting a frequency that is triangular so it develops mass
through rotational intensity and as such tries to withdraw matter if
the frequency is sent with a conductive frequency than the ionisphere
can release energy at any given coordinate and send destructive energy
anywhere.
