Smart-aleck reviews for the book A Million Random Digits with 100,000 Normal Deviates Paperback from Amazon and Goodreads:
> I bought two copies of this book. I find that the first copy perfectly predicts what the numbers will be in the second copy. I feel cheated.
and
> "A Million Random Digits"? HA! They only used 10, and just kept repeating them in different combinations! Don't be fooled!
and finally
> After reading the book a while I started seeing a pattern. I did extensive research to prove my theory. After hours of mathematical modeling I conclusively proved that there is a set of numbers in this book that it not only a pattern, but is outright sequential!
> The top corner of each page (left corner on the left side pages, right corner of the right side pages) was a list of sequential numbers from 1 to 628, all in a row. No numbers are skipped. Even the prime numbers are included! At first you don't notice this because there is only 1 number on each page. But as you advance through the book you notice that the numbers keep advancing by 1 every time you turn the page.
I used to be a dealer too! I ended up dealing blackjack, roulette, craps, bacc, Pai Gow, and many poker variants. I recommend that you read the book Secrets of Mental Math or watch the dvd. To practice, look at getting an app called Anki and make flashcards for yourself. Good luck and have fun!
so need to decide what colleges to apply to
but there are so many colleges out there i'm looking for college match tools
but there are so many college match tools out there that i need a way to find which ones are good & credible
but there are so many articles ranking and comparing college match tools that—
—wait nevermind, i found the perfect resource
A mind for numbers, as mentioned below is very good. There is also a good book for the ‘quicker calculation’ called ‘how to calculate quickly’ that is super easy to dive into and get good value from.

Feel free to post your math questions here and preface it with the text you put in this post. We'll be happy to help you with the nitty gritty details so that you can take the skills you learn for newer and different problems.
Khan Academy and books like this https://www.amazon.com/Basic-Math-Pre-Algebra-Dummies-Science/dp/1119293634 are great (and don't take the title of the book personally haha).
Honestly, I've been trying to rack my brains how you'd get multiple entities calling a global method & all getting the same "random" number.
The only thing I can think of is that the Monks pre-generated a large set of random numbers, - ala this book - and stuck them in an array that is accessed by a modulus of their equivalent of Unix time.
In the past I'd bought a small Dover book that was trying to teach anyone interested how to do fast mental math, with providing the needed methods/tricks and many many many drills to get sharp. I did try for sometime, but then I left it on the side.
Anyhow, this is the book. It might interest someone.
Well, don't beat yourself up, you did a great job!
I would say that from my own experience planning in programming is not easy beforehand, as you often don't know what you end up with before you build it. This comes easier with practice when you start recognize patterns and know your personal understanding which a better suited for your particular style.
Rewriting the code you already have is a great way to find out what style work better for you. I enjoy this algo for this:
Do it.
Do it right.
Do it fast/beatiful/etc
With AoC you have a great chance of following this: first you just try to make all pieces fit together, and then you need to figure out what's the proper way of adjusting them. It's beneficial once you get the answer to rewrite some parts of it then so that you would be able to get more out of it.
ANYWAY sorry for a long message, check this book "exercises in programming styles" if you want to learn more about ways to write python code in different ways. I strongly believe it's more beneficial for beginners than trying to learn data structures and algorithms
There’s a really great book you should read called Zero: The Biography of a Dangerous Idea by Charles Siefe, that goes into the concept of Zero and the profound effects it has had on history and modern technology. Zero: The Biography of a Dangerous Idea by Charles Seife
I mean, if you accidentally touch A Million Random Digits by the RAND corporation you probably won't be the same person, psychologically, once time unfreezes.
Mostly from this book from 1955:

(Not really. But it really was a way for people to have a good source of well randomized but not secret numbers - which has its own uses)
Oh wow, I've never actually talked with anyone who shared that experience. It certainly is really frustrating. Meds don't really help with it, either, even though they've made a huge difference for me in other areas.
I did get a book that improved my mental math a bit, since it taught me new methods that I wasn't aware of. It doesn't help with holding the numbers in my head, but I'm still glad I read the first quarter or so of it. Here's a link:
There is a discount at Amazon. Also check out the reviews!

In the words of Sam O'Nella: Past was a different country. Today it might seem an obvious idea but actually during those days people couldn't grapple zero and his twin brother infinity for mathematical purposes because they are very abstract concepts. Yes, the absence of something and usage as a placeholder was somewhat clear in the above civilizations but first attempts to use zero in mathematical operations what somewhat tried out in India but they couldn't divide by zero. That was one of the reasons why the idea was forbidden in the West. There's a nice book about this.
Humans can't even do good pseudo random, thich is why stuff like this exists. Before computers made pseudo-random easy people would use this book starting at different spots to generate random sequences (if they didn't want to roll dice many times)

The classic old school random number generator https://www.amazon.com/Million-Random-Digits-Normal-Deviates/dp/0833030477
I hear there's a good deal on the book <em>A Million Random Digits with 100,000 Normal Deviates</em>. Might be a scam, but if it's real I wouldn't hesitate to buy it.
I found it! I have no idea what it does but it looks interesting!

This is one of the methods suggested in this book: https://www.amazon.com/Secrets-Mental-Math-Mathemagicians-Calculation/dp/0307338401
It’s a really nice read for doing mental math. The author, Arthur Benjamin, has some really impressive videos on YouTube IIRC
I haven’t read it because I have no time and 2 young children, but I badly want to read exercises in programming style
I would have taken that problem and done (60+40) + 7 + 4. going from left to right is kind of an old trick when it comes to adding, subtracting and multiplying. Given, this isn't exactly what seems to be taught in classrooms today, but it's very close.
Knowing the various tricks and just practice. I wanted to get good at mental math for fun and I saw huge improvements after reading this book and just practicing with apps on my phone or with pen and notebook when I was bored.
Sure there are some people who are naturally gifted but it really does come down to practice. If you have a chance to work on campus as a tutor at all you can then get paid to practice getting quicker.
If you give me a bunch of numbers in sequence out of the <em>Random</em> book, using mine, I'll be able to predict the next number at some point. Are you claiming that the numbers in the book are not random with respect to one another?
I think you need to "scope" (contrived term) the randomness, such that within the fixed 2^19937 - 1 MT sequence, the numbers are not measurably correlated with one another. For cryptography you need a world-scope, so you need to generate novel sequences.
the actual boring stuff.. i dont do popsci crap click bait weak ass shit "10 ways the earth will end!".
This isn't theoretical physics but its ... mathish.. does stuff like this count as popsci crap?
https://www.amazon.com/Zero-Biography-Dangerous-Charles-Seife/dp/0140296476
not sure if I know what popsci articles are.. I assume its like some cute lil blog article about half a concept.. Shit I am not a scholar by any means. I just prefer to pass the night away in my bed reading this stuff while the calming sounds of snores wash over me. (wife snores every so slightly) and I am night owl.
https://usa.newonnetflix.info/info/80067800/s this was on netflix for a bit.. that was an amazingly good series put together. Most would find it boring as hell. I watched that at least 4 times through before they took it off. (provided thats not reading...) I just don't know if i fall into popsci or not.
My guess is Zero: The Biography of a Dangerous Idea by Charles Seife. Very interesting read. Not focused on programming, though.
> I guess that without numbers you could still make reference to relative quantities like "small" or "a few".
For more on this notion, read The Nothing that Is: A Natural History of Zero. Kaplan explores the historical development of zero, and notes various cultures that did not have it. The Greeks, for example, had no word for zero, no number. A Greek might say they had no olives, but a Greek would not say they had zero olives.
Playing with that idea, one could stipulate that other quantities could be represented without mathematics. In the same way that Greeks could have "nothing" but could not have "zero", one might argue that one could have a "single" olive but not have "one" olive.
That all depends on how you draw your categories for what counts as "mathematics" and what counts as "non-mathematic quantities". Because, again, historically there were many cultures that did not have a zero-word, but did have nothing-word.
You shoud read Charles Seife's book Zero: The Biography of a Dangerous Idea.
He lays out the trouble the ancient Greeks had with negative numbers, because they could/would not understand Zero.
The offshoot was that their number lines did not have a zero in the middle, which messed up their addition, subtraction and multiplication of negative numbers.
Excellent read! :)
