Rated 3 out of 5 by from Valuable for young people I am a 78 year-old retired MD. Most of the material in this course I have already learned from life experience. That does not mean that it might not apply to young people ages 18-25. I thought the sections on renting versus buying a home and on credit card payoff were very good. Dr. Omar is very young and he may not know yet that morgage payments in the first few years of a mortgage are mostly interest and those at the end of a mortgage are mostly principal. Or that whole life insurance largely offers level premiums instead of going up at the end of a term. These would be valuable bits of knowledge to have at your fingertips. I would highly recommend this course for young people, but I have to downgrade it for mature audiences.

Rated 1 out of 5 by from Content important but boring I have been a Great Courses enthusiast for years. This is one of the few courses I could not continue after a few selected lessons. The professor uses too many formulas, for instance when he goes through compound interest, when he could simply sum up the mathematical equation and present the result in lay terms without belaboring the long equation itself in minute detail.

Rated 2 out of 5 by from mathematics of Everday Life Not presented well at all. This is the first course that disappointed me. Seems to make things harder and not easier. Conclusions labored and poorly arrived at.

Rated 4 out of 5 by from Math can be useful; not so much as presented here For many, this will be a great awakening to how useful mathematics, really mathematical thinking can be in addressing every day problems. That alone should make this lecture series worth trying out. However, some of the most salient problems addressed in this series could be much better laid out (for ease of understanding), solved, and validated (as a function of varying assumptions) by spreadsheet analysis. I think Professor Omar should consider recasting this course to incorporate what now a day is a basic tool of analysis. By resorting to close-formed solutions and shortcuts., Professor Omar reduces the apparent complexity of a problem, but at the cost of short-changing intuition.

The Magic of Compound Interest

01: The Magic of Compound Interest

Explore the marvel that Albert Einstein called “the eighth wonder of the world”—compound interest, which is the strategy of reinvesting interest rather than paying it out. Simple calculations show that a retirement nest egg of $1 million or more is within reach for those who start investing early. Learn why the average rate of return can be misleading. Also get tips for building a college fund.

How Mortgages Really Work

02: How Mortgages Really Work

Go house hunting, analyzing your monthly and total payments at different mortgage interest rates and terms (15-year versus 30-year). Learn the formulas behind online mortgage calculators to get deeper insight into the snowballing effect of interest expenses across time. Also consider whether it makes more sense to rent than to buy, weighing the hidden costs of home ownership over the benefits.

How to Get Out of Credit Card Debt

03: How to Get Out of Credit Card Debt

The miracle of compound interest that enriches savers can make paupers of those with credit card debt. Learn why this form of borrowing is so risky and potentially ruinous. Explore strategies for paying off credit card debt and consider whether it makes sense to keep credit cards for perks. Then look into college loans, weighing costs versus benefits, and also examining alternatives to loans.

The Real Cost of Commuting

04: The Real Cost of Commuting

Over our working lives, many of us spend a total of a year or more driving to and from the office. Is it worth it? Professor Omar uses simple calculations to assess the true costs of commuting, taking into consideration the relative price of real estate in the city and suburbs, the expense of cars and upkeep, and not least the psychological toll of sitting in a traffic jam day after day.

Understanding Your Health Data

05: Understanding Your Health Data

Investigate numbers you are likely to encounter in the doctor’s office. What do body mass index (BMI) and blood pressure signify? Both correlate measured values with possible health issues. But as you learn, correlation does not imply causation. Also consider questions to ask when faced with statistics for different medical treatments, bearing in mind a phenomenon called Simpson’s paradox.

The Math of Environmental Friendliness

06: The Math of Environmental Friendliness

Apply math to the crisis of global warming. First, define carbon footprint, which applies to greenhouse gases primarily to carbon dioxide. Then test your instincts about the relative impact of recycling, electricity consumption, automobile use, and commercial air travel. Discover that simple measures like carpooling are among the most effective steps you can take to reduce your carbon emissions.

Getting Wise about Health and Life Insurance

07: Getting Wise about Health and Life Insurance

One of the best uses of math in everyday life is gauging how much insurance you need, especially in the confusing realms of life and health coverage. First, analyze two types of life insurance, term and whole, and the advantages and drawbacks of each. Then dive into health insurance, comparing a generic Health Maintenance Organization (HMO) with a generic Preferred Provider Organization (PPO).

Optimizing Your Diet through Math

08: Optimizing Your Diet through Math

Professor Omar tells how his harried life in graduate school led to an unwelcome weight gain. Determined to lose 50 pounds, he used mathematics to come up with a reasonable dieting plan. Learn how to estimate basal metabolic rate and caloric intake, develop an exercise regime, and choose among carbohydrates, proteins and fats. A similar analysis works for gaining muscle or maintaining your weight.

Making Great Estimates with Little Data

09: Making Great Estimates with Little Data

Get the “feel” for the right answer to seemingly intractable problems by using the approach of theoretical physicist Enrico Fermi: break the problem into easy steps and come up with an order-of-magnitude (factor of 10) estimate. Next, learn a statistical approach to problems that obey a normal distribution, using bell curves to get a surprising amount of information from relatively little data.

27 min
The First-Digit Law and Fraud Spotting

10: The First-Digit Law and Fraud Spotting

Discover how mathematics can solve crimes. First, study logarithms, which are the exponents used when numbers are written as a power of 10. Employ this concept to understand Benford’s law, which governs the frequency distribution of digits in common sets of numerical data. See how this hard-to-fake property helps prove financial fraud and also expose cheating in elections.

Voter Math and Gerrymandering

11: Voter Math and Gerrymandering

Gerrymandering is the drawing of electoral districts to benefit one political party over another. See how two mathematical tools reveal when this is very likely occurring. The Polsby-Popper score shows how close a given district is to the optimum compact shape—a circle. The efficiency gap measures the impact of “packing” and “cracking” in different districts, which has an outsize effect on party success.
