Smile Matt's thought for the week

for blog at mattanderson.fun

There is an American integer database online.
It was founded by Neil Sloan.
This database (online encyclopedia) contains
many sequences of integers.

The counting numbers go like 1,2,3,4,5, ...

I have put more than 700 hours of effort into
this database.

I also have two theorems. One states that
the trinomial x^2 + x + 41 never has factors less
than 40 assuming that x is a possitive integer.

It has been proven that there are an infinite
number of prime numbers. This was proven
thousands of years ago.

Also the prime counting function { denoted pi(x) }
where x is a non-negative integer counts the
numbers of primes less than or equal to x. For
example pi(10) = 4. The first four prime
numbers are 2,3,5, and 7.

Also all prime numbers greater than two are odd
This implies that the prime number greater than
three have a difference that goes like 2*n where 2
is a possitive integer.

The next step is to realize that all prime numbers
greater than three have the form six times 'm'
plus or minus one that is (6*n +/- 1).

Then the next next step is to build a 'wheel' for
prime numbers modulo 30, where we consider only
divisibility by 2, 3, and 5.

That is a good place to stop. See teacher (of mathematical Olympiad problems in Virginia US Michael Penn.

Have a nice day.

Both theorems are trivial.

Other than 2, all primes are odd. The difference between two odd numbers is even: 2j+1 - (2i+1) = 2(j-i).

x^2+x = x(x+1) and is therefore divisible by x. 41 is prime and therefore not divisible by anything less than 41.

Matt's thought of the day / week

Prime pages by Chris K. Caldwell is a great resource.
see primes.utm.edu (University of Tennessee at Martin)
Today I glanced at his Sieve of Eratosthenes page.

I used to have a tee-shirt with that in color around here somewhere.

Also, I played pickleball today
see
https://salemkeizerpickleball.com/

good fun. It got the blood fun.

And it was partially non-competitive and social pickleball to boot.

I talked to my sen-sei (Shari Brown) today, but
I did not promise to work out. I practice at home.

Still can't wait for Corona-virus to go away, then we can
lighten up a little bit.

Specifically, I want to associate (be an academic listener) at
Willamette Univeristy more. I have to settle for
Chemeketa Community College. I want to help out.

I give at church and am a member of Elks#2472

Sorry if that was too much information (TMI),
but I needed to vent.

I see my favorite person (wife) in a few hours.
All the chores are done, so this retired person is
tapping on a keyboard. Our she-dog is outside now.
I walked her earlier today.

Have a nice day.
(Attitude is everything.)

PS Thanks for the technical info. I will try to work up a .gif file and post it up. (using Maple and Paint application)

Smile Some know of Fibonacci. Fewer know of Lucas (they are more than names)

Hi again everybody (mostly guys are into mathematics, statistically, from what I have seen)

Some of us are familiar with the Fibonacci Sequence.
Thanks to Google.com we have this reference with a pretty spiral picture.

imagination station Toledo (Ohio or Washington) . org


According to OEIS.org, Lucas Sequence is a thing. see oeis.org/A32

This is my free typing, (fun outlet hobby) (I support mersenneforum.org a little with $money$)

Thanks to readers, moderators, and others.

Have a nice day

If you like engineering try a YouTube link for "Smarter Every Day"
Also, < ladies first >

Cheers
