Scientists See Chemical Bonds Between Atoms
In an amazing work of microscopy, scientists have gotten a high-resolution view of a molecule and its chemical bonds. What’s more, the Lawrence Berkeley National Laboratory researchers got a peek at the molecule as it broke and reformed bonds after undergoing a chemical reaction.
Their images show a molecule, on the left above, which has 26 carbon and 14 hydrogen atoms structured as three connected benzene rings. The molecules on the right are the two most common products that result after the molecule is heated to 90 degrees Celsius.

One week back in Cambridge complete. That makes another eight or so until it’s back to the rainy Midlands in time for Christmas. But that’s a long way off.

As lectures get back into full swing, so will the science. A weird effect of the first year is that it made me less confident about the amount of science I thought I knew. This isn’t to say I learned a negative amount last year, but more like the first year was rather eye-opening to the extent of the subject.

Continuing for a fourth year are the revision posters - the same lovely design as ever: fits nicely on the screen, lots of colours, pleasant fonts, licenced generously. Expect these to begin emerging in the next week or so perhaps.

Yeah. Science.

wildcat2030:

Here is the current set of commandments through the eyes of science, in the form of objective, natural theories that should be believed:

1. Conservation theory: Energy and mass may be neither created nor destroyed but may be interconverted. Thus, creation and final destruction are not relevant.

Conversion: E = MC2

Annihilation: e- + e+ → E

2. Entropy theory: Entropy increases spontaneously. Nature is being dissipated. Improvements, syntheses, organization, and growth require energy at the expense of the environment.

3. Quantum theory: Activity is the product of energy and time.

h = Et

4. Radiation theory: Disintegration of mass is a first-order reaction. Fission applies mostly to large atoms, while fusion applies mostly to small atoms.

5. Particle theory: Particles with mass (such as electrons, protons, and neutrons) give rise to atoms (such as hydrogen, oxygen, and carbon), which give rise to molecules (such as water, quartz, and DNA), which give rise to chemical systems (such as minerals, plants, and animals), which give rise to the universe of objects (such as planets, stars, and galaxies).

6. Evolution theory: Combinations of the kinetic molecular theory, the chirality principle, and the laws of genetics lead to life and the development of species with both inheritance and variation, due to heredity and mutation.

7. Relativity theory: The notion of space-time (simultaneous, consecutive, and complementary events) is defined from the perspective of the observer.

8. Psychological theory: Respect for nature, especially for life, is mandated.

9. Behavior theory: There is satisfaction to be had in helping others toward happiness, which is usually reciprocal in bringing happiness in return. Personal immortality is achieved by the views of others.

10. Ethical theory: For a worthwhile existence, we must strive to maximize freedom with responsibility and find fulfillment with peace and love.

Yep.

A little update

ayraethazeigen:

You deserve a little update since I haven’t posted on Tumblr in a long time.

I’m now a Windows 8.1 user, after reluctantly moving away from Windows 7, which I was previously a long-time user of. I have to say, I’m impressed with what they’ve done, although it does look a little bit silly on my computer. It’s much better suited on touchscreen laptops and tablets.

I’ve been learning German on Duolingo for over a year. Duolingo is the best online language service in my opinion and you should use it right away.

I’ve begun reading Lord of the Rings after being ranted at for not already having done so. The first chapter kinda saved my bacon at uni as well - funny story, maybe later.

The driveway is being done so we can park more cars. I can hear the builders from here - what a racket they’re making.

I’ve begun a series of Downfall parodies entitled “Hitler’s Hit Markers” in which a pro-gamer Hitler obsesses over the in-game hit markers in Half-Reich 2, which manifest themselves in the material world. Watch it on YouTube.

And finally, I gotten around to reorganising my blogs:
main one, Ayraethazide, is for science posts
this one, Ayraethazeigen, is my personal diary
a new one, Ayraethazone, is for gaming posts
Ayréthazide is still my French blog
Ayräthaßeid is my new German blog.

Enjoy!

thenewenlightenmentage

dimethylsulfoxide:

Acetaldehyde C2H4O

  • Appearance: Colorless liquid
  • Molar Mass: 44.05 g/mol
  • Density: 0.784 g/cm(at 20°C)
  • Melting Point: -123.37°C
  • Boiling Point: 20.2°C 
  • pKa: 13.57

Acetaldehyde is one of the most important aldehydes, occuring in coffee and bread. It’s more well known as being the metabolite of ethanol by alcohol dehydrogenase, thought to be the main cause of hangovers. It undergoes keto-enol tautomerism, but only a small fraction of acetaldehyde is in the enol tautomer. Acetaldehyde used to be a precursor to acetic acid, however now it’s more important as a precursor to pyridine derivatives like pentaerthritol. It’s toxic when applied for extended periods, is an irritant on the skin, eyes, and mucous membranes, and is a possible carcinogen. It’s found smoke from cannabis and tobacco.
