To understand how telescopes work, let's ask the following question. Why can't you see an object that is far away? For example, why can't you read the writing on a dime when it is 150 feet away with your naked eyes? The answer to this question is simple: the object does not...

How does a CPQ system work? A CPQ system applies preset rules to user inputs to configure an order (and disallow impossible configurations), determine a price for that order, and generate a quote. It can do instantly what used to be a complicated, manual and error-prone process. What is...
The intensity of these loops implies a density that is as much as 3 orders of magnitude larger than the densities of static solutions to the hydrodynamic equations. It has recently been suggested that these loops are bundles of impulsively heated strands that are cooling through the TRACE pass...
This doesn't happen with stars (here on Earth) because no stars have enough apparent brightness to do so. The brightest star in the sky is Sirius, at magnitude -1.4. The sun is magnitude -26.7, according to SkySafari. If I have done the math right (and it's possible that I didn't...
What is apparent visual magnitude? How are electrons responsible for magnetism? How can a magnetic field be produced around a wire? How does lightning (static electricity) work on an atomic level? (e.g. positive/negative charges, and electrons) Why doesn't electromagnetism affect light? Does ...
How does an astronomical telescope work? How big is the Fermi Gamma-Ray Space Telescope? What are space telescopes and how do they work? What is apparent magnitude in astrophysics? How are constellations used in modern astronomy? How do SETI telescopes work?
And one thing this exercise shows is that it does have a definite shape; it’s not just a point labelled “work hard.” 我的目的是创建一份可供所有领域的人使用的指南。同时我也对通用方法论包含哪些内容充满好奇。最终,这项尝试成功证明:通用方法论的确存在;除了“努力工作”这一条之外,通用方法论...
Bacterial chemotaxis requires bidirectional flagellar rotation at different rates. Rotation is driven by a flagellar motor, which is a supercomplex containing multiple rings. Architectural uncertainty regarding the cytoplasmic C-ring, or ‘switch’, limi
How Does Generative AI Work? There are two answers to the question of how generative AI models work. Empirically, we know how they work in detail because humans designed their various neural network implementations to do exactly what they do, iterating those designs over decades to make them ...
