A visual proof demonstrates the algebraic identity (a^2 - b^2 = (a + b)(a - b)), which is a fundamental concept in algebra."
The statement by Sophie Germain highlights the interconnectedness of algebra and geometry, suggesting that algebra can be represented visually through geometric diagrams."
A visual proof for the mathematical identity (a^2 - b^2 = (a + b)(a - b)) initiated a debate on the reliability of visual proofs.
Critics argue that visual proofs can be misleading, as exemplified by a video falsely "proving" that (\pi) equals 4, emphasizing the need for careful assumptions.
The discussion underscores that while visual proofs can enhance intuition, they often lack the comprehensive rigor of algebraic proofs and may not address all possible cases, particularly with negative numbers.

Tenstorrent and other AI hardware startups are exploring the potential of RISC-V CPU IP as ARM's licensing costs increase, highlighting a shift in the CPU architecture landscape.
The ongoing legal dispute between Qualcomm and ARM over architecture license agreements (ALAs) remains unresolved, with both companies asserting compliance with contract terms, adding uncertainty to the market.
Nvidia continues to dominate the AI hardware market, posing challenges for competitors like Tenstorrent, while discussions also consider the dual impact of large language models (LLMs) on junior engineers' learning and understanding.
In the 2023 "The Crystal Ball Challenge," 118 finance-trained young adults were given $50 to trade the S&P 500 and 30-year US Treasury bonds using news a day in advance, but without price data.
Despite having advance news, half of the participants lost money, and one in six went bankrupt, with an average gain of only 3.2%, due to incorrect market predictions and poor trade-sizing.
The experiment highlighted that even with foresight, successful trading requires skill and strategy, as demonstrated by five experienced traders who achieved better results.
The article explores the difficulty of using financial news to predict stock market movements, emphasizing the complexity and unpredictability of market reactions.
A study showed that experienced traders performed better, likely due to their memory of past events, but overall, financial news is considered mostly noise.
It suggests that long-term trends are more reliable for investment decisions than short-term news, noting a decline in the quality of news sources and the influence of high-frequency trading.
