Wednesday, February 13, Absolute Value Foldables and a 3-Hole Punch Story [If you’re not interested in absolute value, there is a pretty funny story about a 3-hole punch at the very end. Or, maybe it’s not funny. Either way, it was a memorable experience. Our Algebra 1 textbooks introduce the concept of absolute value in Algebra 1. It introduces graphing absolute value equations in the same chapter where graphing linear equations is taught. Of course, I don’t use the textbooks. I keep one by my desk as a reference, but the rest of the books are collecting dust on my shelves.

In fact, I didn’t start studying remedial math until I left the Army at age If there were a textbook example of the potential for adult neural plasticity, I’d be Exhibit A. Learning math and then science as an adult gave me passage into the empowering world of engineering.
This rules states that by dividing your own age by two and then adding seven you can find the socially-acceptable minimum age of anyone you want to date. Take your age, subtract 7, and double it. So for a year old, the upper age limit would be 34 i. With some quick math, the rule provides a minimum and maximum partner age based on your actual age that, if you choose to follow it, you can use to guide your dating decisions.
But how legitimate is this rule? Does it match our scientific understanding of age-related preferences for dating? Does it always apply? How well does the rule reflect scientific evidence for age preferences? Researchers Buunk and colleagues asked men and women to identify the ages they would consider when evaluating someone for relationships of different levels of involvement. People reported distinct age preferences for marriage ; a serious relationship; falling in love; casual sex ; and sexual fantasies.
Based on the figures Buunk and colleagues provided and thus the numbers are only informed approximations , I replotted their data superimposing the max and min age ranges defined by the half-your-age-plus-7 rule.

This is great stuff on Prenups. I have no intention of going into Family Law, but I think maybe we can combine efforts and create an article on Prenups. Not legal advice, of course, but a crash-course on Prenups. I already started on the article for RoK on prenups, but you seem knowledgeable on the topic and maybe we can combine efforts? Are you an attorney?
11) Carbon Dating: the formula (t in years) is used to estimate the age of organic material. The ratio of carbon 14 to carbon 12 in a piece of charcoal found at an archaeological dig is R = 1/10
Always consult a competent professional for answers specific to your questions and circumstances. Weight-Loss Equation Gets a Makeover Almost every diet book, nutrition guide and weight-loss manual includes the information that one pound of body weight equals 3, calories… and then comes the advice that for every pound that you want to lose, you must either eat 3, fewer calories or use up that amount with extra physical activity. If you reduce your average daily caloric intake by calories one less snack pack per day, perhaps?
This would add up to almost The problem with the 3, calorie formula, said Dr. Hall, is that it is predicated on the idea that metabolism remains constant — and it does not. Metabolism is affected by gender, by age, by size and weight loss, and by stress and lifestyle.

Shiva is also known as the Almighty Wisdom. This spot is the Hindu Tilaka, which is similar to the red Hindu Bindi dot on the forehead of females in Hinduism.
With some quick math, the rule provides a minimum and maximum partner age based on your actual age that, if you choose to follow it, you can use to guide your dating decisions.
For example, if you had bacterial cells sitting in a petri dish and you knew that they split about once an hour, using this equation would mean that all of those cells would wait 60 minutes and then all split at the same time. That is not realistic, however. Instead, each bacterium splits at a different time, but after an hour has passed, you would expect them all to have split — and some of the bacteria that had split at the beginning of the hour would be starting to split again.
There is also a limit to how quickly that population can grow. A single bacterium can only split into two, not into four or five. This natural, continuously and gradually growing population is therefore not accurately described by an exponential equation with a base value b of 2, but by an exponential equation with a base value b of e. The constant e has many uses in math, but in science we consider it the base rate of change growth or decay in systems that are continuously changing growing or decaying over time.
Those systems might be a population of bacteria , a chemical reaction , or the decay of a radioactive material. In science, the constant e is intimately connected to the constant k, often called the growth rate constant. For example, most bacteria split more rapidly at room temperature than at near freezing, so the same bacteria will have a different growth rate constant k at different temperatures since there are different environmental conditions.

How David beats Goliath I remember this article. It is about high school girls basketball. I think lots of youth sports balances sub-optimal playing with actually playing something resembling the sport. I know in my early youth leagues, playing defense in the back court was just declared against the rules of the league, because otherwise we would just never learn how to play actual basketball. He began calling one foul after another.
The equation as pointed already is current year – birth year = age If you want a quick way to calculate it in your mind (talking about ages before ), I think the best would be: 1. calculate the years from birth year to 2. add years passe.
Age of the Universe How old is the world? Ancient commentators propose that the world may be simultaneously young and old. Gerald Schroeder One of the most obvious perceived contradictions between Torah and science is the age of the universe. Is it billions of years old, like scientific data, or is it thousands of years, like Biblical data? When we add up the generations of the Bible, we come to plus years.
Whereas, data from the Hubble telescope or from the land based telescopes in Hawaii, indicate the age at about 15 billion years. Let me clarify right at the start. The world may be only some years old.
Ages of Rocks and the Earth
That breaks it down quite well. You should always work towards maximizing all of your four categories. You can use money to improve your looks clothes, healthier food. You can use money to hire a social skills coach extreme situation.
However, equation relates Zhe to Che, and equation gives a formula for Che in terms of simple summations and integrals, so it was direct enough to use those equations instead. The text is pretty clear that it regards those equations to be proven true, although what those proofs are is left sketchy.
Potential of abundant, environmentally harmless energy technology , which already exists My strategy for manifesting that energy event for humanity’s and the planet’s benefit. I w as born in In that same year, I had my cultural and mystical awakenings. During my second year of college, I had my first existential crisis and a paranormal event changed my studies from science to business. I s till held my energy dreams, however, and in , eight years after that first paranormal event, I had a second one that suddenly caused me to move up the coast from Los Angeles to Seattle, where I landed in the middle of what is arguably the greatest attempt yet made to bring alternative energy to the American marketplace.
That effort was killed by the local electric industry , which saw our technology as a threat to its revenues and profits, and my wild ride began. The owner of the Seattle business left the state to rebuild his effort. I followed him to Boston and soon became his partner.
MATH 483 (Spring 2015): Mathematical Modeling
The underlying question is why Euclid did not use this proof, but invented another. One conjecture is that the proof by similar triangles involved a theory of proportions, a topic not discussed until later in the Elements, and that the theory of proportions needed further development at that time. The large square is divided into a left and right rectangle.

The Nora Ephron Theorem of Soulmates: Through this theorem, x will spend her lifetime alone because y is an imaginary expectation of perfection and absolute satisfaction embodied in a human as demonstrated by the CW network and it will never exist, let alone come to New York to save x from herself. In this case, 24x is divided by the number of males that x has encountered within the age span, keeping in mind the exception to this rule, The Billy Loomis factor.
Following the logical schematic exclusions of social interaction with males who plot to murder x in a Freudian revenge model like Billy Loomis in Scream , we must subtract the sum total of the Billy Loomis Factor from overall male-interactions, i. When this is complete, we can divide using the new value of males.
Cannot divide by zero. This equation can be graphed thusly: As evidenced by the graph, x is approaching her limit.

Jul 04, · Define the variables of the equation. The first step to understanding any equation is to know what each variable stands for. In this case, E is the energy of an object at rest, m is the object’s mass, and c is the speed of light in vacuum.
Probability and its engineering uses by Thornton C Fry, Radiometric dating Suppose you want to know how long ago something happened. For example, a forensic analyst might want to know how long ago a dead person ate breakfast. Or an astrophysicist might want to know the age of the solar system. Or an archeologist might want to now how old the dead-sea scrolls are, or how long ago did we evolve a desire for art. How do we tell?
Well, we can build a mathematical model, fit it to some data, and get out an estimate. Our model will consist of some timing process under which a system’s state evolves from some starting point to an end point. The end point will be measured to provide the data. Some secondary source of information will be used to estimate the system’s starting point. Then, based on the timing process, we can estimate how much time between the starting point and the end point. This basic process applies to dendrochronology tree rings , chronostratigraphy dating by rock layers , genetic clocks, magneto and perhaps most famously to radiometric dating.

The decay of radioactive nuclei can be used to measure the age of artifacts, fossils, and rocks. Dating an organic artifact entails looking at its carbon content. Carbon exists in three isotopic forms:, and.
The equation[ edit ] Cumming defines the equation  as is the frequency of the hydrogen fine transition line — the frequency emitted by a neutral hydrogen atom when the spin of the electron in the ground state flips from parallel to the spin of the proton to antiparallel to the spin of the proton. It is equal to Actually, it equals It is defined to be either 0.
Errors in the equation[ edit ] There are several errors in Cumming’s equation. Lack of units in equation[ edit ] The first major error in the equation is the failure to retain units used in the equation. Cumming argues that the numbers provide significant proof of the existence of a creator, yet basic unit: The numbers may match up on one side, on the other , but that doesn’t prove that one pound is the same as one hour.
Other creationists have proven susceptible to errors of identical form. This choosing of two different standards of measurements to declare that they have some meaning with and a number Cumming made up shows no real significance.
