Charts for school
These are the sheets a pupil needs within arm's reach rather than in a bag — the things looked up mid-problem, when going to find the textbook means losing the thread of the problem itself.
Arithmetic first: the times table and the hundred chart. Then notation — Roman numerals, the Greek alphabet as science actually uses it, and the SI prefixes. And two subject sheets: the basic physics formulas with every symbol and unit named, and the solar system with size, distance, year and day set out together.
Above a desk at home, or on a classroom wall. They print on ordinary A4 and A3 — meant to be replaced when they get scruffy, not framed.
THE SOLAR SYSTEM
eight planets · size, distance, year and day
GREEK ALPHABET
24 letters · names and where science uses them
NUMBERS 1 TO 100
the hundred chart · primes picked out in colour
MULTIPLICATION TABLE
1 to 12 · colour intensity = size of the product
ROMAN NUMERALS
seven symbols · ones, tens, hundreds · years
THE VERTICAL PLANET
from the Challenger Deep to the summit of Everest · one scale, nothing compressed
MAMMALS IN TIME
from the first synapsid to us · 320 million years on one axis
VERTEBRATES IN TIME
when each group appeared · five hundred million years on one axis
BASIC PHYSICS FORMULAS
fifteen formulas · every letter explained beneath it
ANIMALS
the main branches — from comb jellies to chordates · who is actually related to whom
THE TREE OF LIFE
who sits inside whom · where animals, fungi and plants actually are
VERTEBRATES
from lamprey to bird · and why "fish" and "reptiles" are not groups
