Experimenting with a Magnetohydrodynamic Drive demo

| April 13, 2021

You can take the boy out of school, but you can’t take school (and learning) out of the boy ( or older man at this point). Over the weekend, I was talking to Brenda about how I’ve been following the NASA feed (tweet below) and waiting for the helicopter to take flight on Mars. The […]

What do you know about the Tennis Racket Theorem?

| February 11, 2021

After reading about the Dzhanibekov Effect and seeing a demonstration, I just had to know more. The tennis racket theorem or intermediate axis theorem is a result in classical mechanics describing the movement of a rigid body with three distinct principal moments of inertia. It is also dubbed the Dzhanibekov effect, after Russian cosmonaut Vladimir […]

Understanding the Pfizer and Moderna COVID19 vaccines

| December 27, 2020

There was an interesting article in Prevention Magazine that explains what the COVID19 or generically the Coronavirus vaccines from Pfizer and Moderna do … AND what their ingredients are. It also details the differences between the two from the standpoint of how cold storage temperatures need to be. Check out the article for the ingredients […]

Prediction: An advancement in superconductivity is coming

| March 25, 2020

It may not come from space in the form of meteorites as mentioned in the story below, but I think the biggest advancement in this decade will be in superconductivity. Physicists have made fantastic advancements in reducing electrical resistance ever since Dutch physicist Heike Kamerlingh Onnes experimented with ferromagnetism in 1911, but getting superconductivity state […]

Give me a lever and I shall move the world … or a mailbox cap

| March 3, 2020

Let’s hope that accidents do not happen in threes? After just getting my quote in order to submit to the insurance company in order to repair our rear fence, our neighbor called to let me know that a generic white-box deliver truck (no license plate) hit our mailbox. Thankfully after looking at the damage, it […]

Semi-Tech Friday: Solar Telescope view of our the Sun

| January 31, 2020

A wide-angle view of the solar surface from the Daniel K. Inouye Solar Telescope is the highest-resolution image of the Sun ever taken, showing details as small as 30 km wide. Seen here are granules, the tops of giant convection cells. Credit: NSO/NSF/AURA Whether it is gazing at the millions of stars night sky (the […]

Do improvements in technology change views on abortion?

| October 29, 2019

It has been 26 years since the U.S. Supreme Court decided on Roe v. Wade. In 1973, our nine justices decided that pregnant women should have the right to legally choose an abortion (would it be different today?). Our national debate has continued non-stop for decades, but the call is getting louder to re-address the issue […]

Wrinkly-Nosed Tooth-Faced Shark – accurate, but not polite

| July 28, 2019

Who wants to go swimming?  The Great White Shark can detect blood in the water up to 3 miles away! Just look at those expensive teeth. I watched several science programs regarding space and the Apollo 11 moon landing these past couple of weeks … and one the other night explaining the Big Bang theory […]

Astronauts may soon be eating goo from their poo

| January 30, 2018

It’s a long way to Mars and there’s "not a drop to drink" (author Mindy McGinnis) or "plop to eat" on the way … so what’s the plan? Since astronauts are already recycling their urine into drinkable water, the next step should be obvious: "Goo made from their Poo." (in observing the current lab conditions […]

Are you prepared for a Coronal Mass Ejection – CME?

| July 25, 2014

Did you know that in July of 2012 that the earth was nearly hit by a CME (video)? According to the Nation Academy of Sciences, the cost of a large CME similar to the July 20, 2012 “storm” could cost $2 Trillion. On July 23, 2012, the sun unleashed two massive clouds of plasma that barely […]

Ten aeronautical advancements thanks to NASA

| May 21, 2014

The Dryden Flight Research Center posted ten technology examples on their site that made a big impact on aviation. Most assume NASA has contributed to our science and engineering advancements, but the debate continues over the the high cost of the taxpayers through government funding the NASA research centers or if the private sector can […]

The lunacy of the super perigee moon

| March 14, 2012

Interesting educational video explaining the super moon a little over a month away in May 2012. A couple of the points were interesting, such as the word “lunacy” (lunar) coming from the folklore of strange things happening under a full moon. The couple centimeters of tidal change also surprised me. It was less than I […]

Windows that generate solar electric power with “buckyballs”

| November 9, 2010

Where would you install photovoltaic solar panels if they were clear? Perhaps they will be in the not so distant future as contemplated by Alyssa Danigelis in her Discovery News article. And here’s a new word of the day: buckyballs – spherical or ellipsoidal cages made up of covalently bonded carbon atoms discovered in 1985 […]

Medical Science: How acupuncture ‘may’ work

| June 1, 2010

The needle pricks involved in acupuncture may help relieve pain by triggering a natural painkilling chemical called adenosine, a new study has found. The researchers also believe they can enhance acupuncture’s effectiveness by coupling the process with a well-known cancer drug — deoxycoformycin — that maintains adenosine levels longer than usual. See article in USNews.com

The ol’ Scared Pepper Experiment

| November 29, 2006

My son came home and demonstrated the “scared pepper” — surface tension of water experiment today. I’m not sure I fully understand the ‘science’ behind the dish washing soap and water, but from an offset printing background we depend on surface tension and even enhance it with isopropyl alcohol or a substitute to dampen aluminum […]
