Unboxing a MONSTER  | Extreme neodymium magnets 👀

Never thought I would unbox a magnet bigger than my monster 6x2", but technology is evolving and I love following along.

Luckily, magnetportal.de was kind enough to donate the magnets featured in this video. They are not cheap! The biggest one alone contains around 3 kg of the rare earth metal neodymium.


The website is German, but I have communicated with them in English and Chrome can translate the website to your language, so don't let it stop you.  ;D

Is the Speed of Sound Constant?

The speed of light is a constant, always traveling at the rate of 186,000 miles (300,000 km) per second. The speed of sound, on the other hand, is much more fickle. For example, sound waves move at 761.2 miles per hour (1,225 km/h) at sea level when the air temperature is 59 degrees F (15 degrees C).

However, heat up the air and they move faster; cool the air, and they slow down.

That's why breaking the sound barrier high in the sky is relatively easy: Temperatures are colder, so a lower speed will do the job.

Interestingly, sound moves very quickly under water, where the molecules are much denser than they are in the air. Their density means that they bump into one another more quickly, which is how sound travels. Sound travels through water at approximately 4,856 feet per second (1,480 meters/sec) -- more than four times faster than its speed through the 💨 air. But because the molecules are denser in water, sound needs more energy (ie. loudness) -- to get moving. That's why faint sounds can't be heard under water like they can above it.

Sounds interesting:

► Sound doesn't exist in space because there aren't any molecules for it to travel through.
► The greatest sound ever recorded 💥 was the eruption of the Krakatoa volcano in 1883. The explosion could be heard 3,000 miles (4,828 km) away.

► A whip's snap is the sound of the tip breaking the sound barrier.

I explain the design and principles behind desiccant based air conditioning. This extremely efficient, DIY air conditioner is inexpensive to build and costs less than one half as much to run as a conventional, compressor based air conditioner.

How Many Galaxies Are in the Universe?

How Many Galaxies Are in the Universe?

A galaxy contains billions of stars, held together by gravity. Within each galaxy, there are planetary systems, like the Earth and its neighbor planets within the Milky Way. But ours is just one galaxy in an astronomical sea of stars reaching farther than the most powerful telescopes can see. We will probably never know just how many galaxies exist, but 3-D modeling by the Hubble Space Telescope over 20 years has come up with a new estimate, published in The Astronomical Journal. In 2016, astronomers studied computer-enhanced deep space images and determined that there are probably around two trillion galaxies in the universe , far more than the previous estimate of between 100 and 200 billion galaxies.

Galaxies far, far away:

֍ The landmark Hubble Deep Field imaging of the mid-1990s gave scientists their first analysis of galaxies, and Hubble's Ultra Deep Field in 2004 added a plethora of faint galaxies, leading to an estimate of 200 billion galaxies.

֍ The newest analysis of deep-space images from Hubble converted the images into 3-D. Using mathematical models, scientists were able to infer the existence of galaxies that current telescopes cannot see.

֍ “It boggles the mind that over 90 percent of the galaxies in the universe have yet to be studied,” the University of Nottingham astronomers wrote. “Who knows what interesting properties we will find ... with the next generation of telescopes?”

They Discovered Something on Mars and Phobos that Cannot Be Explained ..11,924 views


The 5th Kind
Premiered 19 hours ago
The now dubbed “Phobos monolith” is a large object on the surface of Mars's moon “Phobos”. The giant structure stands 90 meters tall. Only 3 meters less than that of the Statue of Liberty Monument in New York. 

First discovered by “Efrain Palermo” who noticed the distinct shadow of the anomaly while analysing images taken from the “Mars Global Surveyor orbiter” lanched in November 1996. This peculiar and solitary large rock was also confirmed by “Lan Fleming”, an imaging sub-contractor at NASA Johnson Space Center. Also Noting the possibility that the monolith is artificial in nature.

Along with the mysterious Monolith photographed on the Martian moon “Phobos”.. A similar looking structure can also be seen upon the surface of Mars...

Environmental Rules Being Rolled Back in the US

In the Science Revolution, Thom Hartmann covers the Trump administration trying to save us from the tyranny of efficient lightbulbs, with environmental rules being rolled back.

Also, author, Tim Wise joins Thom to talk about big AG and its effects on climate change. In our GBU segment,  the  Good is Ireland and what they're doing to help the climate and there is a very very ugly killer in the Mohave Desert, not found yet - we'll be talking about.

Plus, our new Geeky Science segment is inspired by Thom's indoor cat, Kedi, getting loose outdoors, and what he did.

0:37 ENERGY LIGHT BULBS
The Trump administration in the US continues to roll back environmental protections, this time on energy-efficient light bulbs. Is this going to help destroy civilization for profits?

3:15 IS BIG AGRICULTURE DESTROYING THE PLANET?
With special guest Tim A. Wise

Is big agriculture the biggest obstacle to solving climate change? Chemical intensive agriculture is kicking our planet and actually contributing to world hunger.

The deforestation in Brazil is contributing to CO2.

Why is the US federal government promoting the industrializing of land and pushing the same in other countries? Small scale farmers around the world are being pushed to increase in size and use chemicals produced in the US. Seed companies want farmers to not save seeds for the next year but buy fresh seed every year. There is nothing climate-smart or sustainable about that.

Timothy A. Wise joined Thom to explain the policies and what is going wrong.

The Good - Ireland Planting Trees
The Bad - Broadcast News
The Ugly - The Killer of 42 Wild Burros

16:08 SCIENCE FACT OF THE WEEK
According to scientists at NOAA's National Centers for Environmental Information - July 2019 was the hottest month on record for the planet. The average global temperature in July was 1.71 degrees F above the 20th-century average, making it the hottest July in the 140-year record. The previous hottest month on record was July 2016. Nine of the 10 hottest Julys have occurred since 2005 -- with the last five years ranking as the five hottest. Not surprising - There is also record-low sea ice. Average Arctic sea ice set a record low for July, running 19.8% below average -- surpassing the previous historic low of July 2012.
