Why is some science fiction so good at predicting actual science?

Don’t miss our next video! SUBSCRIBE! ►► http://bit.ly/iotbs_sub

Do Ray Bradbury, Arthur C. Clarke, Jules Verne, Philip K. Dick, Hugo Gernsback, Robert Heinlein, or Isaac Asimov hold a candle to H.G. Wells when it comes to correctly predicting the future of science via science fiction?

And why does some science fiction do such a good job of predicting the future in the first place?

This organic chemistry video tutorial explains how to calculate the specific rotation of an enantiomer given the observed rotation, the pathlength, and the concentration of the solution. It discusses how to determine if a molecule will show optical activity based on its chirality. It also provides the formulas needed to calculate the optical purity and enantiomeric excess. Those formulas can be used to calculate the relative percentages of the R and S isomers.

Anthropic just pulled off one of the fastest growth stories in tech history jumping from $1B to $4B ARR in just seven months. For comparison, Snowflake, once considered the fastest-growing SaaS company ever, took six full quarters to double from $1B to $2B.

So how did Anthropic do it? Not through traditional SaaS subscriptions, but through usage-based API pricing. With developers burning 10–50x more tokens for code generation compared to regular chats, token-based pricing has become a goldmine. One product launch can cause token usage to skyrocket and suddenly a customer is spending $100K+ per month, with zero sales calls involved. This is usage-based growth at its purest: seamless onboarding, explosive developer adoption, and revenue scaling with actual customer value.

While OpenAI chased headlines, Anthropic quietly built enterprise-ready APIs, integrating directly with AWS and Google Cloud. This video breaks down why usage-based pricing, when done right, can outperform traditional SaaS — and how Anthropic just rewrote the playbook for monetizing AI infrastructure at scale.

This chemistry video tutorial provides a basic introduction into complex ions, ligands, and coordination compounds. A complex ion typically consist of a transition metal cation bounded to ligands which can be neutral molecules or ions. The number of ligands attached to the transition metal ion is known as the coordination number. This video explains how to determine the oxidation state of the transition metal ion in a complex ion and within a coordination compound. A coordination compound consist of a complex ion and a counterion. The counterion may be a cation or an anion. This video briefly discusses werner's theory of coordination compounds and the concept of primary valence and secondary valence as it relates to the transition metal ions in complex ions.

So today Craig is going to look at political ideology in America. We're going to focus on liberals and conservatives and talk about the influencers of both of these viewpoints. Now, it's important to remember that political ideologies don't always perfectly correspond with political parties, and this correspondence becomes less and less likely over time. So, sure we can say that Democrats tend to be liberal and Republicans tend to be conservative, but we're not going to be talking about political parties in this episode. It's also important to note, that there are going to be a lot of generalizations here, as most peoples' ideologies fall on a spectrum, but we're going to try our best *crosses fingers* to summarize the most commonly held viewpoints for each of these positions as they are used pretty frequently in discussions of American politics.

Today Hank begins to teach you about Philosophy by discussing the historical origins of philosophy in ancient Greece, and its three main divisions: metaphysics, epistemology, and value theory. He will also introduce logic, and how you’re going to use it to understand and critically evaluate a whole host of different worldviews throughout this course. And also, hopefully, the rest of your life.

Nachos are great...if you are among the lucky ones whose bodies can digest them. When digestion goes according to plan, the small intestine performs most of your chemical digestion in the duodenum, while accessory organs including the liver, gallbladder, and pancreas contribute enzymes that all but finish the job. Then your large intestine, which is actually shorter than the small intestine, tries to extract the last bit of nutrition, including the occasional attempt to turn nachos into energy, which for most humans, ends in gassy failure.

In which John Green teaches you how the Civil War played a large part in making the United States the country that it is today. He covers some of the key ways in which Abraham Lincoln influenced the outcome of the war, and how the lack of foreign intervention also helped the Union win the war. John also covers the technology that made the Civil War different than previous wars. New weapons helped to influence the outcomes of battles, but photography influenced how the public at large perceived the war. In addition, John gets into the long-term effects of the war, including the federalization and unification of the United States. All this plus homesteading, land grant universities, railroads, federal currency, and taxes.

Kære venner
Jeg har sådan glædet mig til at dele denne fantastiske nyhed med jer.

I samarbejde med Gonge Danmark udgiver vi inden længe 25 af mine værksteder incl. alle tilhørende konkrete materialer, så de kan stå i værkstedskassen klar til brug.
Jeg vil i nærmeste fremtid gennemgå hver af de 5 værkstedskasser (5 værksteder i hver), så følg med her på kanalen og også gerne på Instagram, hvor jeg vil vise eksempler på værkstederne i brug i mine klasser.

Glæder mig vildt til at høre, hvad I synes om dem :)

In which John Green teaches you about the Little Ice Age. The Little Ice Age was a period of global cooling that occurred from the 13th to the 19th centuries. This cooling was likely caused by a number of factors, including unusual solar activity and volcanic eruptions. The Little Ice Age greatly impacted human social orders, especially during the 17th century. When the climate changed, and the weather became unpredictable, the world changed profoundly. Poor harvests led to hunger, which led to even less productivity, which even resulted in violent upheaval in a lot of places. All this from a little change in the temperature? Definitely.

Kære venner
Kan du og dine elever løse en Rubiks Cube?

Det kan I hurtigt få lært, og der er super meget god matematik og hygge forbundet med løsningen af sådan en terning.
Eleverne får øvet sig i mange vigtige elementer. Først og fremmest i at koncentrere sig og prøve igen, når det ikke lige lykkedes med det samme.
Men også i at forstå og anvende de algoritmer der gør løsningen mulig.
Og de bliver så stolte, når det lykkes at løse første step eller den første hele side... og med tiden måske hele Cuben.

I denne video kan du se min vejledning til løsning af Cuben, og du kan gratis hente de 8 steps på min hjemmeside lige her:
https://anettekmatematik.com/loes-en-rubiks-cube/

Brug kortene som separate værksteder sammen med videoen her. Hav gerne en ipad klar, så eleverne hurtigt kan finde det rigtige sted i videovejledningen og løse det pågældende step sammen med mig.
Rigtig god fornøjelse.

Del gerne denne video og link til min hjemmeside med kolleger, elever og forældre. Måske der er flere der vil lege med.
