@compoundchem
1803 marks the birth of #QuantumTheory.#JohnDalton quantized mass when he postulated his essentially correct #AtomicTheory. ✅
-
@compoundchem #JohnDalton is the true founder of #QuantumTheory because his #AtomicTheory correctly quantized MASS to explain observations in #chemistry 🧪 almost a century before #MaxPlanck quantized energy to avoid the ‘ultraviolet catastrophe’ :oh_no_bubble:.

Intense weekend working into this year's Merk #CompoundChallenge. Did we design the best route? Idk, but we sure had lots of laughs.

Very informative graphic about the differences between the different types of light bulbs.

Interesting that the group 4 elements on the @compoundchem infographic
Carbon, Silicon etc, whereas Wikipedia
https://en.wikipedia.org/wiki/Group_4_element
Suggests group 4 is Titanium, Zirconium, Most periodic tables are group 1,2 on the left, then there is a jump over the transition to group 3, Boron, Aluminium, Transition elements are numbered IIIB, IVB (which wikipedia lists as group 4) 2nd group of the transition elements.
So which is correct here, or does it depend on the periodic table you are looking at?

You could get something looking like grapes.
Apples "have an especially profound amount of genetic variation", apples are heterozygous. Lots and lots of competing possible DNA expression and mutation.

Note the dangers of mixing bleach or hydrogen peroxide with other cleaners.
"It’s also very important not to mix bleach with other cleaners. There’s no need to anyway, as it does a very effective job on its own. And if you do, there’s the risk of the cleaner reacting with the bleach and generating toxic chlorine gas. We’re trying to kill the virus here, not you."

This morning I replaced the infographic on Group 2 elements with the infographic for Group 3 elements. Both are from @compoundchem
Will be changing this weekly, as to go through the periodic table

STEAM Café & Discovery Centre,

Paignton,
Devon
TQ4 6AAWebpage: https://zleap.net/community/steam
have some excellent infographics, including one on each of the groups of the Periodic table. Over the next few weeks, I will be displaying these in the discovery centre, changing to the next one each week.
By rotating posters /infographics,s we keep displays fresh and different each time people visit.

Today is #NationalDNADay 🧬
Here’s a look at what makes up DNA’s structure and how the genetic code is translated into proteins: https://www.compoundchem.com/2015/03/24/dna/

@karlauerbach @compoundchem Public health and solid waste people use the word “putresible” in regulatory language. Food, dead animals, and other waste that are capable of putrefaction (putrescible) must be disposed of weekly or twice-weekly with whatever else is defined as “garbage” locally to avoid odor and fly breeding. I didn’t know that there was any specific smelly chemical associated with the term. Non-putrescible solid wastes may be disposed of less frequently and are covered by many terms that may differ by locale—the #USPHS used to use “garbage” for any mixture of waste that included putrescibles, “rubbish” for non-putrescible waste, “municipal solid waste” for either from residential & commercial sources, “debris” for various kinds of inert wastes, and “refuse” or solid wastes for all of it. Flood wastes are a special case, since no matter what it started out as, it’s been contaminated by a mix of putrescible and toxic wastes of largely unknown types and concentration. #Helene #Cleanup

Yes, washing hands with basic soap is the best. But if you don't have access to soap and water, learn to distinguish between the various types of hand sanitisers.

@compoundchem happy birthday, very interesting. Let me share you one #boardgame about #Chemistry produced by #science oriented designers , the rulebook always comes with a dedicated explanatory addendum and can be used at #school . They have covered several topics already . Happy 2024.#Periodic

Today is #WorldPulsesDay and kidney beans feature in this edition of #PeriodicGraphics in C&EN on toxins in common fruits and vegetables - did you know that uncooked kidney beans contain a toxin that can cause nausea and diarrhoea? https://cen.acs.org/biological-chemistry/natural-products/Periodic-Graphics-Toxins-fruits-vegetables/98/i46

Chemistry is often thought of as boring, and its explanations do lean dry and arcane, but it is a technology sufficiently advanced as to be indistinguishable from magic for the average person. https://www.compoundchem.com/2023/10/04/2023nobelchemistry/

@compoundchem I never fail to learn some new #chemistry from every #CompoundInterest #infographic. But the ones that attract my attention the most are those expounding on the chemical compounds in different aromas, such as 👃 🌸 👉 https://www.compoundchem.com/2015/02/12/flowers/.
I think this is because it is the sense of smell that I associate with my own chemical discoveries, as recounted in “Chemical Eye 👁️ on Aesthetics.” 👉 http://www.sitnews.us/MacDougall/021205_macdougall.html
