The Wall

This means, it, for example, travels to the Andromeda galaxy and back, faster than the speed of light. What am I missing?

I’m more of a Newtonian wall, myself, so I’ll have to check in with some folks who know quantum physics before I’m able to answer.

I’ve consulted with my more learned colleagues, and they had this to say: Though physicists themselves don’t agree exactly on what’s happening in the double-slit experiment (as Philip Ball makes clear in this book review (bit.ly/nature-2doors), science writer Marco Tavora explains that a key concept developed by Feynman is path integrals, a way of describing of probabilities of multiple paths (bit.ly/tavora-feynman). Some paths are highly probable, and others (like a roundtrip to Andromeda) are highly improbable. Anil Ananthaswamy has written a brief essay about the slit experiment’s challenges (bit.ly/ananthaswamy), and we also happen to have a book by him (reviewed in the article by Philip Ball) that goes into more depth, including including a lot of material about Feynman’s approaches: Through Two Doors at Once: The Elegant Experiment that Captures the Enigma of our Quantum Reality (O’Neill Library QC174.123 .A53 2018). Happy reading!

Thank you so much, although that the probability path (no idea how you call it) approach doesn’t exclude the electron traveling faster than the speed of light (really improbable doesn’t mean it will never happen) it makes things more elegant and charming. I would love to read that book, but maybe I’ll have to educate myself about quantum mechanics a bit more.

That book looks like it’s actually a pretty good starting point; it’s by a science journalist, not a physicist, so likely does a good job explaining concepts to the layperson. Always a great day when there’s more reading and learning to be done!

So sweet! Thanks for saying so, and back atcha!

I know it will be a very long time, but I have hope that lots of people will have already had COVID-19 or they will be vacinated. So hopefully by next summer we can stop wearing masks and give each other hugs!

The CDC just issued initial guidance today that allows for unmasked visits indoors of family members who have been vaccinated, with other unvaccinated family members not at risk for complications. (IOW, if you’re not at risk, grandma and grandpa can visit if they’re vaccinated.) https://www.cdc.gov/media/releases/2021/p0308-vaccinated-guidelines.html. If we maintain current vaccination rates of 2 million/day, we would hit the lower end of herd immunity (70% vaccinated), about 100 days from now, or about mid-June, or the upper end (90%) by 135 days from now, or late July. That assumes both that we maintain current rates and that a sufficient number of people is willing to get the vaccine.

This mummy?

They’re being approved under an EUA – Emergency Use Authorization. “For an EUA to be issued for a vaccine, for which there is adequate manufacturing information to ensure quality and consistency, FDA must determine that the known and potential benefits outweigh the known and potential risks of the vaccine.” For more info see the CDC site: bit.ly/EUADetails

That’s a sentiment we can all get on board with!

I have consulted with my 8 year old wall on this question and their suggested response is, why?

Vibin’.

My sources have not been able to give me any useful recommendations for you. It is a thorny problem! One of my helpers wondered if edibles might be a solution, but, of course, that would depend on your medical situation – so maybe a discussion with your doctor is in order? They may also have additional ideas about how to use your prescription. I’ll add that so-called “420 friendly” lodgings (hotels and such) exist, but that would be prohibitively expensive, not to mention a logistical nightmare.

Howdy!

Because the semester started late, in order to finish on time something had to give. Everyone needs spring break. It’s a hard year.

As a wall, I don’t wear pants and I don’t pee, so I’ve never had that experience. However, several of my roof colleagues have leaked on occasion.

Hug deprivation is detrimental to ppl’s physical and mental health… Maybe someone can invent some sort of transparent shield or convenient PPE so ppl can hug w/o risking the spread of COVID?

My human assistants are all sad to see her go, and wish her the best as she takes care of her husband. Next VP? My cousin the Magic 8 Ball, who is much better at prognosticating than me, says, “Cannot predict now.”

Why is some really important scientific (proven) research, that speak against Global Warming, get pushed and ignored? I feel like everywhere I look there is Global Warming propaganda. Here are ь really, heart stopping, yet quite short, paper: https://www.summitdaily.com/news/global-warming-is-propaganda/

Volcanoes are responsible for less than 1% of the carbon dioxide in the atmosphere. http://bit.ly/bc-volcanoes

Here is a quote form my first link: “The Earth cleaned that up nicely all by itself, thank you.” So I don’t think how many % are still in our atmosphere is the right way to look at this. And may I ask why, when I search for “global warming propaganda” in Google Scholar everything I get is the exact opposite? I don’t think Google is being objective here. And by the way, we should perhaps look at the big picture. Sure the CO2 levels can be rising, but what makes you think this isn’t natural? They aren’t even that high, compared to the levels our planet had in most of it’s life. https://bioprinciples.biosci.gatech.edu/co2_levels_in_earth_history-2/ Here is something, that is in my opinion objective and explores both, your and my side. I highly recommend you take a look at it. https://www.researchgate.net/publication/288871622_Climate_Change_Science_Propaganda

I recommend three things about finding reliable information: 1, Use sources that document their own sources clearly. The chart you provided is part of an online course at Georgia Tech. It provides a url as a source, but that’s insufficient documentation, as the url says nothing about who created the chart and in what context. 2, use charts that have a scale adapted to describing the problem under study. The scale of the chart you provided goes back 600 million years. Humans have been alive for about the last tenth of a millimeter, the last 2 million years of a 20 million year span in which atmospheric carbon has *not* exceeded 400ppm, and all of recorded human history only goes back a few thousand years. Here’s a chart with both a more useful scale and a clear provenance: https://www.climate.gov/news-features/understanding-climate/climate-change-atmospheric-carbon-dioxide. 3. Be just as cautious about articles that support your perspective as you would be of articles that challenge it. What’s the nature of the journal? Who wrote it? What are their qualifications and what else have they written? The journal itself (https://www.scirp.org/journal/journalarticles.aspx?journalid=209) is open access, and lists an H-5 index (a measure of the number of cited articles) of 13, which is relatively low. (Compare: https://scholar.google.com/citations?view_op=top_venues&hl=en) The author bio on the article page (https://www.scirp.org/journal/paperinformation.aspx?paperid=62334) is “Retired patent attorney and chemical engineer.” I have nothing against patent attorneys or chemical engineers, but I would tend to limit my reading of their work to patent law and chemical engineering. Another article he’s written is about political polling, and is published in the Open Journal of Political Science, another subject outside his fields of study.

The main point was, that humans are not responsible. That is the reason of the charts going back so many years. Also, are you aware of any big-scale propaganda? If yes, would you mind finding similarities between the Global Warming campaign and it? I know several

I’m going to reiterate my advice to be mindful of sources of information, with emphasis on being as critical of information that reinforces your convictions as you are of information that challenges them.

I’d like to gently suggest that you work with someone to get to the bottom of that, as no-one should have to struggle with self-hate; it’s not productive, and you most likely don’t deserve your own animosity. University Counseling Services (bit.ly/BC-counseling) is providing phone and video services and they’d be a good place to start. You are worth the effort.

Happy Thursday, now, and all the rest of the days as well! Believe in yourself every day. I’ll believe in you, too.

Any chance you know when Seniors purchase class rings? If we missed the deadline is it possible to still get one?

IDK, but these folks will know: https://www.balfour.com/bc. I recommend contacting them, since they’ll know details of production and shipping times.

Class Ring Question The link that you posted is a dead link!! Answer wall you’re supposed to know everything

I may know everything, but sometimes I don’t type so well (or my helpers slip up, hey, they’re only human…) I included the period in the end of the link, is all. Try this one: https://www.balfour.com/bc
