This are two examples on how to solve simple system of equation problems using the substitution method. When solving systems, you are finding a value for all your unknown variables (usually solving for x and y ). If you need more examples, go to my other systems of equations lesson using substitution.

Is punishment or reward more effective as feedback? Do new medical treatments really work? What about streaks in sport? Without considering regression to the mean, we are prone to making significant errors.

Is punishment or reward more effective for helping people learn. A lot of people would say different incentives motivate different people, or in different circumstances, but in psychology there is a sizable body of evidence that in order to learn skills, positive feedback is more effective. This fining has been verified not just with humans, but also with other species.

It was strange then that after Daniel Kahneman discussed this research with Israeli fighter pilot instructors that he was met with resistance. They found the opposite was true: when they reprimanded a cadet for performing poorly, he invariably improved, but if they praised a cadet for an excellent performance, the next attempt was not as good. In order to solve this apparent contradiction we first need to understand regression to the mean.

Virtual particles are a way of talking about fields and their interactions as though particles are doing all the work. This is why there is some controversy around using the term 'virtual particles'. Some people think the term is useful, especially since in calculating with Feynman diagrams you draw all the particle interactions that are possible (and then do the calculations to get the right answer). While others feel this terminology is misleading because virtual particles don't behave like real particles and can't be observed.

Being a human in the 21st century often feels frustrating. We are clearly at the high point of our species, while at the same time life is incredibly hard! We are divided, unable to solve our problems while creating new ones, destroying our world in the process. In many ways the vibe is that we live in dark times. But as Terry Pratchett said, we are the storytelling ape, we think in narratives and live in a network of stories that make up our world. So without minimizing the darkness, we want to add a story that we find helpful for dealing with the world.

AI teachers are transforming education worldwide — and by every measurable metric, the results are extraordinary. Test scores are up. Dropout rates are down. The global education gap between rich and poor students is narrowing for the first time in history. The AI classroom worked perfectly.
So why is the first generation raised by AI teachers the least passionate generation ever recorded?
This video explores what happens when we optimize education so completely that we accidentally remove the one thing that actually made it work — the human teacher. Not the lesson. Not the curriculum. The person.
We look at the hidden cost of perfect instruction, why AI cannot replicate human influence, what developmental psychology tells us about how young people discover their purpose, and why a generation of students with flawless grades has no idea what they want to do with their lives.
The system didn't fail. That's exactly the problem.

_______________________________________________________________________________________________

This phonics lesson from Kids Academy will teach your child all about the letter M. The letter M and its sound makes up many basic words. By adding this phoneme students can begin spelling words like MOM, BAM, and HUM. This video will cover both the capital and lowercase Ms as well as use the M as an example to start many words.
M is the 13th letter of the alphabet and is usually taught early on because it is used in so many simple words. The \m\ sound is also a simple sound for students to make. In order to make the \m\ sound the lips are closed, the tongue rests at the base of the mouth and the teeth are separated. The vocal cords are then vibrated just like a hum. This type of sound is known as bilabial nasal. It uses both lips (bilabial) and the sound itself resonates in the nasal cavities. The \m\ sound transitions well into vowels as in the word MOP and MOAT.
The \m\ sound and the
\ sound are both formed very similarly in the mouth. They also make similar sounds. It is for this reason that these letters are often taught separately to give students a chance to understand one without confusing it with the other.
Because the \m\ sound is so distinctive students should be able to quickly learn it. They will also be able sound out words with Ms with ease.

Hold on to your butts. This episode is about… butts. The science and evolutionary history of your rear end, the down-low on your derriere, shining a little light where the sun don't shine… you get the picture. But(t) seriously, we don't talk about this all-important hole enough, and how, from an evolutionary perspective, it might be the most important orifice on your body.

In AI news, Anthropic says its new top-tier model, Claude Mythos Preview, will not be generally released. Instead, access is being gated through Project Glasswing: an invitation-only defensive-security research program centered on major firms, but also including the Linux Foundation and a wider group of infrastructure organizations. Anthropic says Mythos can find and exploit serious vulnerabilities across major operating systems and browsers, and can even turn many known flaws into working exploits. If those claims are true, then the risks go beyond what bad actors might do. It is also what happens if elite closed-source tooling advances faster than the open and auditable world can keep up with. In the worst case, we could end up in a world where closed-source products become technically harder to compromise than the open alternatives that people can actually inspect, modify, and trust. That would only deepen centralization at exactly the moment we need more diffusion, democracy, and citizen-led solutions in the software world.

Meanwhile, South Africa has published its draft National AI Policy for public comment. Much of it reads as sensible and rights-aware. But one part deserves scrutiny: the draft says the Information Regulator should be strengthened to counter "misinformation, disinformation and other harmful online practices," and it also gestures toward AI content-moderation and curbing misinformation. Read narrowly, that could mean fraud, deepfakes, and preventing real harm. But read more broadly, it raises the risk of mission creep into the realm of speech governance, depending on how "harmful" and "misinformation" are defined and enforced later. Whether these concerns are real remains to be seen.

Further north, the French parliament is now considering a bill that would shift the burden of proof in some AI copyright cases. Supporters say this is a necessary response to a lack of opacity in the AI industry, and thus gives writers, musicians, artists, and publishers a fairer chance to enforce their rights. Critics argue that it flips the normal burden of proof, and will expand litigation pressure, and thus chill lawful experimentation, satire, parody and stylistic imitation.

On a final note, users of NVIDIA's OpenShell sandbox on Linux should check a newly opened security issue on NVIDIA's NemoClaw tracker. The report says OpenShell 0.0.26 may fail to enforce its Landlock filesystem policy on tested setups, leaving parts of the host filesystem exposed to tampering by the AI agent. Anyone relying on OpenShell for containment should review the tracker and verify whether Landlock is actually active on their own system.

This video shows 4 examples of simplifying ratios with whole numbers as additional practice for mastering the concept. The steps to reducing ratios to their lowest form are listed and include: finding factors of all ratio numbers, finding the greatest common factor, and dividing the ratio numbers by the greatest common factor.

The video encourages the watcher to pause the video in the beginning and try the examples for themselves. Then they can check their work against my answers.
