If you’re like most adults in the U.S., there’s little doubt your mailbox — the snail-mail version — is regularly inundated with credit card offers. The vast majority of the offers declare your pre-selection, or pre-qualification, for its credit card. Even better, some note you have actually been pre-approved for its best offers and rates. But what exactly does this mean, to be pre-approved? And what does it mean for you specifically? Are these prefixed words simply a marketing ploy […]

How to Prepare for Severe Weather Season When spring arrives in some parts of the U.S., so does extreme weather like tornadoes and thunderstorms. And as fall and winter approach, many homeowners begin bracing themselves for wildfire season or hurricane season, followed by winter storm season. Although the types and the severity of these extreme weather events varies widely depending on where you live, it’s important for all homeowners to stay informed and to be prepared. With more people spending […]

One of the most powerful strategies I’ve found for improving my life is the idea of systems. Basically, rather than setting a goal for yourself, you develop a system of some kind, a set of daily actions that gradually nudge you toward that goal. For example, instead of saying “I’m going to lose 100 pounds this year,” you ask yourself, “What can I sustainably do each day to lead to gradual but significant weight loss over the course of this […]

When you buy renters insurance, you probably have one primary reason for making that purchase: you want to protect your belongings. Renters don’t have to worry about rebuilding their homes after a disaster, but that doesn’t mean fires, theft and other perils can’t impact their belongings. Fortunately, renters insurance gives you a way to protect your furniture, clothes and electronics. Thanks to off-premises coverage, your policy can extend to your belongings even when they are not at your rental. Still, […]

What kind of impact do you have on the environment? According to the U.S. Environmental Protection Agency (EPA), a typical passenger vehicle emits 4.6 metric tons of carbon dioxide per year. One ton is equivalent to a balloon that’s about 30 feet in diameter, so if you were to visualize the metric tons emitted per person per year, picture a balloon 138 feet in diameter. We created a car emissions calculator to help you understand how you’re directly impacting the […]

Every few months, Sarah and I clean out our pantry and cupboards. We pull out absolutely every item in there, sort them into sensible groups, make sure everything in there is still good, and put the good items back in there in a sensible fashion. Usually, at the same time, we make a bunch of meal plans for the next few weeks to use up some of the items that have been there for a while. The thing is, you’ll […]

As summer approaches, people start looking forward to spending time outdoors. Children especially get excited about playing outside. While parents should be encouraging their children to be active, it is important to be aware of the potential dangers they could face in their outdoor environments, especially in the summertime. In fact, the National Safety Council indicates that more preventable, accidental deaths happen during the two months of July and August each year than during any other two-month period. Without exception, […]

The spread of coronavirus has shaken the economy with mass layoffs and increased uncertainty. As a result more and more Americans are finding themselves in mounting debt. In 2018, the American household debt reached an all-time high at $13.21 trillion across 300 million people. But for those with a diagnosable mental illness, debt has an even more detrimental impact.  One in four adults will experience a mental health event at some point in their life. The relationship between debt and […]

One complaint people often make when they settle into a more frugal lifestyle is that their life begins to take on a feeling of “sameness,” in that each day feels more similar to the others than it did before they made frugal changes to their life. (This same shock is being felt by people under stay at home orders, too, for similar reasons.) I’ll give you a great example of this. Many people settle into a routine of eating out […]

Mother’s Day is coming up this weekend and, for a lot of us, it’s an event that won’t be like normal. The possibility of many Mother’s Day traditions, like a nice dinner at a restaurant, isn’t even possible in many areas, and social distancing closes the door on many ideas, whether it’s enforced in your area or not. So, what options are there for Mother’s Day that don’t involve just ordering a gift online somewhere and having it shipped to […]

One positive side effect of this period of social distancing is that, over the past two months or so, many people who have found themselves working from home and unable to go out — teachers, computer programmers, professors, accountants, office workers, engineers, managers and many others — have found themselves saving a ton of money. I’ve had several friends express quite a bit of pleasure at the amount of money building up in their checking accounts since they can’t go […]

Tornadoes can happen in any state in the U.S., and with more than 1,200 occurring annually, they are not uncommon. If you live in Texas, Kansas, Florida, Oklahoma, or Nebraska — the five top states for tornadoes — be sure your homeowners insurance has tornado coverage.  Even if you don’t live in a state where tornadoes are common, it’s worth noting that the only state that hasn’t had at least one tornado in the past decade is Alaska. No matter […]

Many Americans — and people all across the world — are facing a personal finance apocalypse right now. A lot of people are dealing with a sudden job loss or a major cut in hours. Some people are riding out unemployment insurance, while others may not even have that. Many people are facing unexpected and sudden medical expenses. If you add that to the fact that almost four in five Americans were living paycheck to paycheck before coronavirus arrived on […]

Relativistic length contraction is theoretically predicted but not directly tested, which lead to incorrect interpretation of the theory illustrated by Bell’s spaceship paradox and Ehrenfest paradox. But these paradoxes can help us designing experiments to test length contraction. Ideal direct experimental proof should contain the following steps: 1. Measure the tested object’s length at rest,...

Astrophysical jets are flows of matter that moves at relativistic speed. They are opportunity to see length contraction in action. An astrophysical jet is analyzed to explain the length contraction effect. Astrophysical jets are ejected from compact objects such as black holes. https://en.wikipedia.org/wiki/Astrophysical_jet#/media/File:M87_jet.jpg is a photograph of the jet ejected by the supermassive black hole...

Length contraction is used to explain Michelson–Morley experiment. A Michelson interferometer is formed by 2 perpendicular arms. The journey of light along the vertical arm gives the time dilation law. The journey of light along the horizontal arm gives the length contraction law. The derivation scheme of the length contraction law is: 1. The time...

In Special Relativity relativity of simultaneity is the fact that 2 simultaneous events occurring in a stationary frame does not appear simultaneous in a moving frame. For example, in Einstein’s train thought experiment 2 simultaneous flashes of light on the platform do not appear simultaneous for the observer in the train. But relativity of simultaneity...

Einstein’s derivation of the Lorentz Transformation is purely theoretical. This study shows how it is related to the physical phenomenon of time dilation and length contraction. The Lorentz Transformation was first derived using the conditions of time dilation and length contraction. Later, Albert Einstein has given a different derivation of the Lorentz Transformation by using...

In a short preprint The super-Sasaki metric on the antitangent bundle, I explicitly show how to lift a Riemannian metric and an almost symplectic two-form on a manifold $latex M$ to a Riemannian metric on the antitangent bundle $latex Pi T M$, which is, of course, a supermanifold. This example was first given in Modular...

The short preprint The super-Sasaki metric on the antitangent bundle, has now been extensivly rewriten and improved. I wrote about the first draft here.
