My recent Decoded Science article, “Statistical Risk of Airplane Crash versus School Shooting“, responds to a reader’s question.

School Safety versus Aviation Safety

Would it be safer to spend a day in school or take a flight in an airplane? What do the statistics show? Are you more likely to engage a lawyer to sue for criminal assault, or an airplane crash attorney?

I found statistics for the USA, but not for Canada. Here in the Great White North, the only school shooting that comes to mind was the 1989 École Polytechnique massacre in Québec. In Manitoba, the “Gimli Glider” may be the most famous Canadian aviation safety incident of 1983.In 2005, Air France flight 358 skidded to a halt on Toronto Pearson airport. In both these incidents, all passengers survived.

Thank you for reading about my publicity for comparing the statistical risk of airplane crashes versus school shootings.

This past week I answered a reader’s question to Decoded Science with the online article, “Practical Uses of Matrix Mathematics“. That reader wanted to know about using matrices in daily life; but so much depends on one’s own day-to-day life.

Learn to Apply Matrix Math

Actually there are many, many fields in science that use matrix arithmetic. These include statistical applications (from sociology through “hard sciences”), chemistry and physics, and electrical engineering. As well, the discipline of mathematics studies how matrix math works: the rules, the tricks, and the relationships with other disciplines.

Before applying matrix mathematics, you have to learn the math; and also learn about the discipline to which it applies.

I just glanced over some courses offered by the University of Waterloo, where I earned my B.Math degree several decades ago. The Math faculty introduces matrix mathematics in the linear algebra courses; this provides a strong theoretical basis for matrix math. Meanwhile, an Electrical Engineering class approaches matrices from the practical side, where you solve simultaneous equations to analyze electrical circuits. In my view, the University of Waterloo remains one institutions of higher learning in Ontario.

Abrupt discontinuation can cause dangerous spikes in blood pressure – especially when taken with a beta-blocker. 7) DiureticsDiuretics come in three classes:Thiazide Diuretics -Loop Diuretics -Potassium-sparing Diuretics -Diuretics work by causing the kidneys to excrete sodium and water canadian cheap viagra in the urine – resulting in less fluid in the blood and react. Sex in men depends on mood When men are burdened with responsibilities they refrain from having sexual cialis viagra sale intercourse. Ayurveda considers sexual pleasure as an important point that you need to take it 3 hours before the buying cheap cialis sexual activity. It is not supposed buy canadian viagra to be kept in a cold storage or any such thing.

So if you’re heading for university in some discipline, check the course lists for topics like “matrix” or “vectors and matrices”; “linear algebra”; or “simultaneous equations”. If that’s part of your future, plan to enjoy manipulating rows and columns in matrices.

Thirsty for more information on this topic? Start with the paperback “Linear Algebra for Dummies” from Amazon Canada or Amazon USA. Mary Jane Sterling introduces vectors and matrices, simultaneous equations, and explains how to compute determinants and eigenvectors. Plus, she finishes with “real-world applications”… which is just what my Decoded Science reader wanted.
