Smartphones and Kids

Posted on by

The rise in teen suicide, juvenile crime and child anxiety can be traced (at least in part) to the use of smartphones. I have heard child psychiatrists acquaint giving a smartphone to a child with giving them a heroin needle. So why would a loving parent get one for their kid? The answer, of course, is peer pressure, and a contest of wills between parent and child.
‘My Fellow Parents Have Betrayed Me’ How it feels when your allies in the fight for a phone-free childhood buy one for their fifth-grader.

The answer, must be legislation. Give parents a break and allow kids to only have “dumb phones” until eighth grade. Only if we do this as a culture, do we have a chance at saving out kids. Ohio just passed and is implementing a “no phones” in school policy. We will see how that works. If behavior and academics improve, then I see no reason to not implement a kid smart phone ban.

And on This Day Let Us Consider…

This is the beginning of a current article in Scientific American…

“From World War II until 2024, the US stood unchallenged as the scientific leader of the free world. Across practically every discipline — physics, materials science, astronomy, chemistry, biology, medicine, geology, etc. — American scientific missions and initiatives, often in collaboration with European, Canadian, Asian, and many other global partners, brought us new advances and breakthroughs, paving the way for generations of scientists to thrive. In a society that values facts, scientific truths, education, and the public good, this recipe led to multiple generations of continued breakthroughs and advances.
Since late January of this year, however, all of that has rapidly changed. Many of the most valuable scientific organizations in the world, including NOAA, NASA, the NSF, the CDC, the EPA, and the FDA, have experienced a set of unprecedented internal attacks.

Funding streams have been terminated.
Grants that have been successfully competed for and won have been pulled.
Fellowships and scholarships have been revoked.
Contracts have been broken.
Thousands upon thousands of employees have been terminated, often in defiance of court orders.

And now, at the start of the second half of 2025, a new budget is on the verge of becoming law, which would largely eliminate science as we know it across universities and colleges, research institutes, and national labs. This isn’t a horror story; this is a real-life nightmare for the most educated and skilled American workers of all: scientists.”

This is a sad thing indeed. And a real betrayal of our country. Hope all that “winning” was worth it Trumpers.

Long COVID in Kids

Posted on by

“An article recently published in JAMA Pediatrics (or, the Journal of the American Medical Association Pediatrics) presents findings from a study suggesting that Long COVID, a condition where symptoms last at least 3 months and up to several years after a SARS-CoV-2 infection, has surpassed asthma as the most common chronic health problem affecting children.”

Don’t bother vaccinating them, they’ll be fine.

I Could Watch This Guy for Hours

Posted on by

I first heard about “Mend It Mark” when there was an outcry from the Youtube community that he had received a take down notice from a “high end” audio manufacturer called Tom Evans. It became a right to repair issue and many Youtubers posted a copy of the video and dared Tom Evans to try and take them down. Anyway, Mend It Mark is a really good channel of a very competent electronics tech doing his job. Like furniture and tool restoration videos, it is soothing. Here Mark does a quick, but thorough repair on a 90’s Technics Amp.

The Tom Evans thing is pretty neat. He basically reverse engineers a piece of audio kit that has every part “potted” (identifying numbers have been erased or covered on every component) and created his own repair manual. Amazing talent this guy has. The video was restored and is here…

Killing Solar Power in Ohio

Posted on by

From the Plain Dealer…

Ohioans and their elected representatives have killed enough solar development to roughly power the state’s three largest cities in the three years since state lawmakers passed one of the nation’s most stringent restrictions on new solar development.

Those political efforts to block or preempt 2,000 megawatts of new energy coming online are the product of 2021 legislation that gave new power to project neighbors and local elected officials to stop development.

Many of these projects were killed by local Republican officials doing the bidding of the oil and gas industry. Just last week, developers behind a proposed 500-megawatt solar farm in Logan County withdrew their permit application, ending a $500 million development. Regulatory staff recommended the Ohio Power Siting Board reject the application, given opposition from local activists and Republican political power at the state and local level.

Enough power to power all three of Ohio’s biggest cities, with no carbon emissions. The Republican party is not a forward looking party. It is a party that holds Ohio (and the country) back. As they force America off the world stage they leave greater and greater openings for China to be a world leader.

Clean Drinking Water More Cheaply

Posted on by

More Cheaply? Doesn’t sound right. Anyway, This new technology relies on a 3D printing method to make membranes for reverse osmosis desalinization plants. As long as it doesn’t create another problem with the used membranes (unlikely) any help in lowering desalinization cost would be very helpful.

Ionic Thrusters

Posted on by

Back in 2002, our Physics teacher introduced me to a student who wanted to build an ionic thruster. I had never heard of one, but I was able to tell the young man where to obtain a high voltage power supply (and give him a long lecture about safety). A few days later he popped by to show me a device constructed of balsa wood, aluminum foil and stainless steel wire that would levitate (it was anchored by its power supply wires) when connected to about 15,000 volts. I was kind of blown away to say the least. That young man is an engineer now and ionic thrusters have continued to be developed by NASA. Here is a further demonstration…

Great series.

Why We Can’t Focus

Posted on by

One of my favorite books is Neil Postman’s “Amusing Ourselves to Death”. Postman eerily predicted the current age of social media as a natural progression of the age of television, and he did it back in the early 80’s. This video does a fantastic job of laying out one of Postman’s best arguments. It is exactly how I feel about the subject.

He mentions a book called “The Shallows” by Nicholas Carr. I’ll be ordering that one as well.

Lidar

Posted on by

LIDAR, LiDAR or LADAR, an acronym of “light detection and ranging” or “laser imaging, detection, and ranging” is a method for determining ranges by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver. (Wikipedia)
When I was at Kent as a Geology major this technology was just coming into play. Field work was rapidly going to disappear. Now using these tools available from USGS (thank you USGS) we can see our own neighborhoods in a new way.
