Beginner Books is the Random House imprint for young children ages 3–9, co-founded by Phyllis Cerf with Ted Geisel, more often known as Dr. Seuss, and his wife Helen Palmer Geisel. Their first book was Dr. Seuss's The Cat in the Hat (1957), whose title character appears in the brand's logo. Cerf compiled a list of 379 words as the basic vocabulary for young readers, along with another 20 slightly harder "emergency" words. No more than 200 words were taken from that list to write The Cat in the Hat. Subsequent books in the series were modeled on the same requirement.Beginner Books had only four titles in their catalog in 1958. Two years later, they were earning 1 million dollars a year. Random House acquired Beginner Books in 1960 and was the largest publisher of children's books in America.

    Easy geometry problem, please give me a hint...

    I have calculated the height of the segment using the Pythagorean Theorem and that's currently where I am right now. I don't seem to find any equations that can help me. Though I might be not trying hard enough or using the wrong words because I'm not really fluent in mathematical terms as you...

    Would someone mind checking my proof? Intro Real Analysis

    Here is my solution. I used mathjax to type it up in Overleaf. I feel like it makes sense, but I also have a feeling I might have "jumped the gun" with my logic. If it is correct, I would appreciate feedback on how to improve it. Thanks!

    Python What downloads are required to work with Python?

    Hey everyone! This might be a bit of a dumb question, but I'm not familiar with much in the programming world. I know a few languages that I've learnt on my own (online) or through a course in school (MATLAB). When it comes down to coding outside of matlab or a website, I'm not sure where to...

    Studying Should I start with a basic physics book without calculus?

    Hi, I want to start learning physics as I have never studied it in my life but have now taken an interest towards it. I have quite literally zero knowledge on physics, so assume I haven’t taken middle school or high school courses on physics, as I haven’t. I’m 17 currently, but that shouldn’t...

    How to learn physics if I know calculus but zero physics?

    Hi, I have decided I like to learn some physics as I know absolutely zero physics and also including chemistry or biology, and I’d like to learn a bit of all 3, to the high school level perhaps. It seems that from, what I’ve read if I want to learn chemistry, I’ll first have to know physics, and...

    The use and meaning of the three beginning physics equations

    The first three equations i was given is as follows: Vf = V0 + at Vf^2 = V0^2 + (1/2)at^2 x = V0*t + (1/2)at^2 [why do they sometimes use y instead of x or V0,y?] I don't understand in what situations i would use them in nor do i understand why you us V=gt or X=Vx*T. (i understand g can is...

    Studying Am I supposed to understand everything in a formula?

    When studying equations, formulas, laws - am I supposed to understand each bit of information ? For example, let's take Fick's law: So I can memorize the law and I can tell with words what is "t", what is "x", what is "D", and so on, but I don't truly understand why is one divided with the...

    B Coefficient of Restitution

    Where does the Coefficient of Restitution equation come from, in terms of the Conservation of Energy? The measure of efficiency is the velocity after the collision divided by the velocity before the collision, but how does it get to that point? I'm trying to view this focused on an object that...

    What is the relation of mass and power?

    How should power be calculated in a situation where distance and time are both given, as well as mass. At first, I was thinking of just using W=Fx (force as mass x 9.8) to solve for work, and then I would take the solution for work and put it into P=wt. Does this make sense? That's my best...

    Intro Physics Why are the Feynman lectures not good for beginners?

    Is it because it is more rigorous than books like Halliday and Resnick? Or maybe you need to digest those books as a prerequisite for the feynman lectures? Or maybe people don't believe a regular person could digest the feynman lectures as a introductory level physics book? If someone is a...

    Can someone help me chose a motor for my hand drill?

    Background: (I'm a beginner) I plan on using PCV pipe for the main body. The drill's purpose will be to install screws into pre-cut groves (basically a motorized screwdriver). These screws will be only a couple centimeters tall so the motor will only need a moderate amount of torque and rpm. It...
