To Teach Children Financial Skills, Focus on Math, Not Money

Math, not financial strategizing, is the skill most needed to handle the important financial decisions that all adults face.

Math, not financial strategizing, is the skill most needed to handle the important financial decisions that all adults face. And studies show that when schools require extra math courses, students get better at things like managing credit, avoiding foreclosure, and negotiating salary.


In a survey of schools that implemented personal-finance courses, however, Harvard Business professor Shawn Cole found that graduates showed no statistical difference within a 15-year span either before or after the personal-finance programs began.

"A lot of decisions in finance are just easier if you’re more comfortable with numbers and making numeric comparisons," said Cole.

Helping your children overcome the stigma of talking about money is an important first step, according to Cole, and it falls on parents to find the crucial balancing point. In many households, discussing the family finances is uncouth, or parents themselves may be uncomfortable.

Yet teaching children to see every event through the lens of cost-benefit analyses risks encouraging anti-social behavior, possibly losing friends who can help during those tough times in life when money can't.

Best-selling author and financial planner Bruce Feiler explains how parents can approach the touchy world of finance with their children:

"Actually try to limit the influence of money. After doing all this research — in our home we have chores; we have allowance. We do not overlap the two. Because if you do, it turns out the kids will do the chores just for the money. You get an allowance as part of being a member of our family. ... The point is when the kids are young, when the stakes are lower, let them make their own mistakes..."

Hints of the 4th dimension have been detected by physicists

Physicists have understood at least theoretically, that there may be higher dimensions, besides our normal three. The first clue came in 1905 when Einstein developed his theory of special relativity. Of course, by dimensions we’re talking about length, width, and height. Generally speaking, when we talk about a fourth dimension, it’s considered space-time. But here, physicists mean a spatial dimension beyond the normal three, not a parallel universe, as such dimensions are mistaken for in popular sci-fi shows.

Does conscious AI deserve rights?

If machines develop consciousness, or if we manage to give it to them, the human-robot dynamic will forever be different.

  • Does AI—and, more specifically, conscious AI—deserve moral rights? In this thought exploration, evolutionary biologist Richard Dawkins, ethics and tech professor Joanna Bryson, philosopher and cognitive scientist Susan Schneider, physicist Max Tegmark, philosopher Peter Singer, and bioethicist Glenn Cohen all weigh in on the question of AI rights.
  • Given the grave tragedy of slavery throughout human history, philosophers and technologists must answer this question ahead of technological development to avoid humanity creating a slave class of conscious beings.
  • One potential safeguard against that? Regulation. Once we define the context in which AI requires rights, the simplest solution may be to not build that thing.

A new hydrogel might be strong enough for knee replacements

Duke University researchers might have solved a half-century old problem.

  • Duke University researchers created a hydrogel that appears to be as strong and flexible as human cartilage.
  • The blend of three polymers provides enough flexibility and durability to mimic the knee.
  • The next step is to test this hydrogel in sheep; human use can take at least three years.
