Things of Science #262 — Probability

Things of Science unit from August, 1962 on probability. I’ve already scanned in a unit just like this one.

Things of Science #257 — Geometric Models

Things of Science unit from March, 1962 on geometry. They indicate it was a popular unit and, as of 1962,  has been re-issued several times. The copyright on the front page indicates 1949, 1956 and 1962. (Note also that it is re-done again in the 1969.)

There are a few cards that came with the unit that were printed on a stiff card stock. Those are reproduced on the last few pages of the booklet below.

Things of Science (1969) — Geometric Models

Geometric ModelsMaybe it was the Summer of Love?  Things of Science started to get more colorful in 1969 — swapping out the usual yellow-gold paper for other colors (although admittedly, a less-than-inspired gray here) .

Additionally the “logo” for Things of Science changed as well. See for yourself on page 1 of the booklet linked below.

This unit takes on geometry but explains some familiar concepts in a hands-on way. Very cool.

The last few pages of the booklet contain scans of the cards that came with this unit. Additionally there was string, a push-pin, etc. Contents here:

Things Of Science (1969) — Abacus

Things of Science (1969) AbacusProbably the longest booklet I have encountered in a Things of Science unit to date. Small beads made for a small abacus you could build with this unit. The booklet (below) goes into lot of detail on using the abacus and it’s history.

Things Of Science #306 B — Topology

Things of Science Logo

An unusual Things of Science, both for the size of its booklet (a full U.S. letter size; 8.5″ x 11″) and also for how text-heavy this unit is.

The subject of this unit, topology, is a fairly complex concept in mathematics and Things of Science, as usual, gives it a very thorough treatment. Perhaps this unit was intended for a fairly sophisticated and advanced learner. While they approach the subject in easy to grasp terms, it is hard to see twelve-year-old me being very engaged.

Here is the diagram-heavy booklet (not too many “things” in this unit though):

Things of Science (1969) — Probability

Things of Science 38This Things of Science must be newer than the previous ones I posted. It isn’t numbered, The booklet too has gone from the larger 5″ x 6″ format to a narrower 3″ x 5″ (and nicely stapled now).

The “experiments” in this unit read more like math problems (not surprising, I suppose). But, again, like the best of Things of Science, the math is approached very practically — that is, by rolling dice, picking colored disks at random out of a box, etc. So it brings a very down-to-earth understanding of a complex topic.

This unit was also published earlier in 1962.

Here is the booklet:
