Today in the classroom:

First year chem fell apart on yesterday's test. Like, badly. We're going to have some hard conversations today in class about what needs to happen to get back on track, especially athletes who need to remain eligible. Everyone retests on Thursday.

Second year had a rough review day, so they also had some hard conversations about how to prepare for difficult tests. They get grace, we'll do one more review day and test tomorrow.

#chemisty #teaching :cupofcoffee:

Back to school today after a surprise snow day yesterday. I didn't sleep well, even with the long weekend, so I'm going to power through the day today.

First year chem is doing test review over the atomic structure. Test tomorrow.

Second year chem will be analyzing PES diagrams to connect empirical data with the electron structure theory.

Random #chemisty question. So, some washers used to secure an antique sewing machine (1880's sewing machine, probably placed in the now disposed portable box in the 1920's or 1930's) has some yellow precipitate or corrosion/tinge to it. Curious if any chemists have any ideas on what might be the reaction there... (possible something lead-based?)

Some thoughts about the best #physics (and #chemisty) demos for "walk by" table demos

https://rhettallain.com/2023/08/30/thinking-about-the-best-large-crowd-physics-demos/

Burning away their future.

I've spent over a decade thinking about, studying, and speaking out against human-caused ecological negligence. That negligence takes multitudes of forms. For example, local people burn biomass such as farmers burning piles of tree branches on their land or neighbors burning piles of plants in their gardens (colloquial terms such as "bonfires", "campfires", "BBQs", etc). For the relatively ignorant and small-minded, these localized air-polluting activities may not seem like a big deal. However, humans taking part in activities that emit air pollution causes both diseases (proximate) and will ultimately cause human societies to collapse (eventually) due to the effect of climate heating (caveat. If humans don't change their air polluting behaviors - and stop doing them).

During my time of environmental activism, I've had many different ideologies of my own. I used to be more naive and believed that people only need to be informed about how air pollution causes disease and climate change. However, to inform someone about the harm caused by, for example, inhaling smoke pollution, that someone must:

1. Have the background knowledge to understand what you're talking about (e.g., chemistry, biology).

2. Care.

Or

3. Care and trust what you are saying (trust the source of information. e.g., a Doctor or scientist can be a less or more trusted source of information).

Unfortunately, many people don't have the required background knowledge (e.g., scientifically illiterate) and trust the wrong sources of information such as the adverts from the businesses that are selling fuels and their associated politicians - also known as #GreenWash #disinformation or phrasing it simply, lying so as to make a profit (fraud \ corruption)

However, when speaking out against air pollution I did use to think that the response I received from people was because, in general, humanity didn't care. However, I came to realize that that idea didn't make sense (in general).

To explain why that didn't make sense I will briefly describe what air pollution is and its effects on humans and the environment. (generally) Air pollution is caused by burning the element carbon. All living organisms (Plants, Animals, Fungi, Bacteria, Viruses, etc) are carbon-based lifeforms (including humans). When carbon is burnt that chemical activity emits gasses (e.g., carbon dioxide) and carbon particles (e.g., smoke) into the air (atmosphere, generally). Whilst there are other chemicals involved during the burning process, the majority of harm is caused when humans inhale carbon particles. Once a human has inhaled, for example, smoke or traffic pollution, the carbon particles travel into the lungs and from there into the bloodstream. In a dense form, carbon particles can be seen with the unaided eye, for example, smoke, when more dispersed carbon particles can't be seen (unless viewed through a microscope. Hence the term, microscopic particles).

Once in the body, carbon particles cause damage to humans. It's a long list of diseases, however, an example of a few: cancer, asthma, dementia (i.e., brain damage), and heart attacks, strokes (cardiovascular diseases in general).

For a general overview of the medical evidence of the effects of wood smoke inhalation see the Doctors and Scientists against woodsmoke pollution website https://www.dsawsp.org/

Finding scientific evidence about how deadly is air pollution isn't difficult, but, folk generally aren't that interested in that evidence (it's not a cute cat picture or sports cars). https://www.sciencedirect.com/search?qs=air%20pollution

So, as mentioned, I once thought that the reason why, for example, people didn't respond as expected when I stated the fact that, for example, air pollution causes childhood disease or climate change, was because humans, in general, didn't care.

However, people do of course care about their own health. Therefore, something else is going on. What is the underlying psychology that makes people thoughtlessly ignore the (not pleasant) information that would improve their own health outcomes? Nobody wants cancer, asthma, heart disease, or dementia.

Air pollution causes dementia https://pubmed.ncbi.nlm.nih.gov/?term=air+pollution+dementia

Generally, what's going on is humans' fear, ignorance and denial are causing people to not learn how air pollution affects their health or the climate.

So, many people are thoughtless (ill-informed) regarding how the effects of how their own air-polluting activities are harming their own health and causing climate heating. Whilst there are many examples of this ecological thoughtless negligence, a trip to, for example, many #uk campsites will prove my point. There you will see many adults choosing to sit around campfires or BBQs, oblivious to the fact what they are doing is harming themselves by inhaling wood smoke pollution (although, having fun whilst doing it).

Humans have been burning wood for hundreds of thousands of years (if not longer). Evidently, many humans enjoy doing it. They enjoy the fire, the smell, the experience. However, besides air pollution causing human disease, air pollution also damages the environment. From acid rain to climate change, humans are burning away their future.

However, if humanity was choosing and focusing on the general solutions climate change would have been mitigated.

A recent Ars Technica article covered the impactful work of Shahar Keinan and what she and her team is doing at POLARISqb. The brand new episode of QuBites is quite timely then and I have to say I was really impressed. This work could save the lives of many people with much faster drug discovery thanks to #QuantumComputing. 🙏

#introduction Hello #chemtoots and #sciencetoots I'm a photochemist, researcher and father of a 2year old. I find fluorescent molecules exciting and like sharing their beautiful colours and other science stuff. Still figuring out this new #chemiverse #chemisty

@heydebigale Hello from Melbourne. I work in #analytical, #biological and #environmental #chemisty Pictures show some of my work. A periodic table by electronegativity, 3D printed NMR spectra and the Chirality-2 teaching app for #Organic chemistry.

As a non-chemist, I just look at the pretty diagrams

This video started a good discussion over on my friends feed. So far no one has answered it and I dont want to give away the answer to anyone else (please CW your answers) but the question is this:

Why is it when you burn a piece of steel wool it gets heavier, but if you burn a log it gets lighter.
