What's here?

For no other reason than I thought it may be useful, I have assembled here a collection of pdf charts and timelines covering topics in science and history. The charts available will be expanded, updated and improved regularly. They are free for you to download and use.

These charts and timelines may be of interest to:

• home-schoolers
• people interested in evolution and biology
• those with an interest in history

Professional-quality Poster-size Charts

Our professional-quality charts are single-page poster-size: either A1 or A0 size. You can print these on to any paper size that your pdf reader supports, using the Shrink to Fit option. I suggest you run down to your local print shop, such as Kinkos, and have them run off a copy. It's not expensive.

• The Roman emperors. The best timeline available of the Roman emperors (A1 paper size).
• The Christian Liturgical Calendar. Suitable for Catholics, Anglicans and Lutherans. As exemplified by the year 1999/2000 (A1 paper size).

Informative But Not Pretty Poster-size Charts

These charts are informative but not pretty. We're working on them.

• The Tree of Life: Every Creature that has Ever Lived (A1 paper size).
• The Tree of Life: Vertebrates (A0 paper size, really big).

Informative But Ugly Charts

Our older charts are works in progress: multi-page files, suitable for printing on two or more A4 pages. You have to print out the A4 sheets and stick them together. Sorry about that. For those using US paper sizes, just check the Shrink to Fit box on your pdf reader.

Science Charts

Here we have a whole bunch of evolutionary tree of life charts. I became interested in phylogenetics and biology a few years ago, and for my own interest decided to make a few trees-of-life, just to keep clear in my own head the current state of biological thinking from the Eucarya to the Primata.

I am not a biologist, just an interested spectator, so I claim no authority for these charts. I've picked up bits and pieces from Paleos; that immensely unreliable source, the Wikipedia; and stuff from Thomas Cavalier-Smith's work.

• The Tree of Life: Eucarya.
• The Tree of Life: Metazoa.
• The Tree of Life: Bilateria.
• The Tree of Life: Chordata.
• The Tree of Life: Tetrapoda.
• The Tree of Life: Mammalia.

History Charts

Here are our first historical charts:

• The Presidents of the United States of America. Includes party affiliation, and each president's ranking by quartile, from best, to mediocre, to worst.
• The Chronicles of the Old Testament. A timeline with all the Old Testament kings and prophets.
• The History of Early Christianity. A timeline with all the Church Fathers and early Christian heresies.
