QAMA Calculator
http://qamacalculator.com/
A calculator that "thinks only if you think, too," QAMA
requires the operator to first enter a reasonable estimate.
QAMA encourages rounding and rapid backoftheenvelope
reckoning, but does not tolerate errors of magnitude or sign,
or of basic operations with single digits.
Ilan Samson, "inventorinresidence" at the California
Institute for Telecommunications and Information Technology
(Calit2) at the University of California, San Diego, purposely
priced his device low to motivate routine use, and get people
"into the habit of never calculating without thinking and
understanding," irrespective of their ages.
Learn more about QAMA's scope, tolerances, builtin "alert"
system that flashes red lights when in "nonthinking"
(conventional calculator) mode, and other special features at
the qamacalculator.com site, now accepting its first orders.

"A couple of days ago I logged into Facebook to see that 4 of
my friends all had a birthday that day. Being the nerd that I
am, I immediately tried to figure out the probability of this
occurrence. I have run through a couple of scenarios, (binomial
and 493 simultaneous independent events) both of which have
much smaller probabilities than I would have thought. I also
tried applying the birthday paradox logic, but just confused
myself, so I thought I would throw it out there for some
summer fun."

Naming Symmetries for Charity
https://www.maths.ox.ac.uk/naming_symmetries
An Oxford mathematician has discovered some significant new
symmetrical objects — and for a donation of £10, you can
name them.
Donations go to Common Hope, an educational charity supporting
and empowering children and their families in Guatemala
through education. See the list of previous donors, learn more
about certificates issued and autographed by mathematician
Marcus du Sautoy, and more.
Sautoy serves the University of Oxford as its Charles Simonyi
Professor for the Public Understanding of Science and Professor
of Mathematics.

"Finland is the current fashionable flavor for math, yet their
language is truly atrocious for counting. The number 18 is
kahdeksantoista, meaning '8 of the second,' which is perhaps
sillier than our dyslexic 'eighteen.' I am not optimistic any
arithmetic simplifiers will catch on in the USA as it, Liberia,
and Myanmar refuse to embrace base ten."
