I’m sure the meme here was an attempt at humor on the author’s part, but the serious side of learning/teaching the subject is worth a comment.

I would never introduce even elementary physics to a kid who’s not proficient in first year algebra, and preferably algebra 2, with its functions, logarithms/exponents, trigonometry, etc.  That’s why Earth science and biology are taught before physics.

I doubt the little darlings shown at left have too tight a grasp on 8th, 9th, and 10th grade math.

While I don’t believe that God is going to interview me when I leave this planet, I get the point here.

Here’s a meme whose purpose is to bash EVs, using a combination of lies and half-truths.

Scientists have been conducting “well to wheels” studies that compare EVs to internal combustion engines since the late 20th Century and have concluded that EVs have a large advantage that is growing with each year. A few facts:

Extreme low-carbon energy sources that contribute to our grid-mix include nuclear, solar, wind, and hydro.

The most conscientious EV owners charge their cars by overbuilding the solar PV arrays on their rooftops.

The amount of diesel that goes into our grid and charging our EVs is almost zero.

The number of coal-fired power plants in the United States has fallen roughly in half in the 15 years since 2GreenEnergy was launched.

I recommend “A Word a Day” for those wishing to expand their vocabularies.  But in fact there are other features on this site to look forward to, including “A Thought for Today,” quotes from notable people in history born on this date.
This from French philosopher Voltaire (21 Nov 1694-1778):  It is lamentable that to be a good patriot one must become the enemy of the rest of mankind.”
It’s reminiscent of what Einstein said on the subject when asked if he considered himself a German or as a Jew:
“It is quite possible to be both. I look upon myself as a man. Nationalism is an infantile disease. It is the measles of mankind.
“I am against any nationalism, even in the guise of mere patriotism. Privileges based on position and property have always seemed to me unjust and pernicious, as did any exaggerated personality cult.”
As true as all this was in the past, it’s far more impactful in the days of nuclear weapons proliferation, climate change, and the prospect of world fascism.

My theory on the subject here is that Trump’s lies are so common and blatant that they do not damage the adoration that his supporters have for him.  They are willing to justify his complete lack of honesty with malarkey like, “Oh, all politicians lie.”

Until you realize that he is a career criminal/conman, all this false equivalence makes perfect sense.

In healthcare, we have people who think they know better than the doctors and medical scientists.

In climate change, it’s arguably even more offensive.  Here, we have the climate deniers who claim that the true cause of our warming temperatures is solar activity–or gravity–or God knows what else–and that it has nothing to do with the consumption of fossil fuels.

It’s just amazing that the people who have been applying the scientific method to get answers here for the last 40 years are so confused, especially given that the truth is so obvious to Trump loyalists.

It’s a question of who you are and how you define winning.

Suppose a) you’re filthy rich, b) Trump’s economic policies, e.g., tariffs, don’t send us into a tailspin, c) you couldn’t care less about the wellbeing of the common person or our country’s future as a competitor in global markets, d) you have the resources to avoid the consequences of environmental collapse, and e) you’re indifferent to American democracy, then it’s possible that, when 2028 rolls around, you’ll count yourself a winner.

If even a single piece of a – e isn’t true, you’ll wish you had done something to prevent Trump’s re-election in 2024.

The words of journalist Dan Rather here remind us of something happening here in the United States that doesn’t seem to be changing over time.  Americans’ perceptions of Donald Trump fall into one of three categories:

He’s a vile criminal, and the thought of his leading this formerly great nation is nauseating.

He may not be a fine person, but his policies are so far superior to the Democrats’ that we need to overlook any of his imperfections.

God sent us Trump, an honest and strong person, to lead us away from the communist, woke sissies that would otherwise take over this nation.

Perhaps the most important criterion for determining if a certain group is a cult is as follows: Its leader is always right.  In other words, if it appears to you that the leader made a mistake, it is you who are confused, ignorant, etc.

It’s good to see this concept gaining ground.

We have the resources to deal with each of our civilization’s woes: starvation, destitution, ignorance, baking temperatures, and so on.  All we need is the political will.
