In higher dimensions, objects like cubes and spheres exhibit properties that defy our three-dimensional intuition, such as the inner sphere's radius extending beyond the cube.
The volume of a unit 𝑑-sphere decreases with increasing dimensions, and most of the sphere's surface area is concentrated near the equator.
The "kissing number," or the maximum number of spheres that can touch another without overlapping, is precisely known in only a few dimensions, with solutions in eight and twenty-four dimensions using special lattice structures.
High-dimensional spaces exhibit counterintuitive properties, such as the decreasing volume of a unit sphere as dimensions increase, which challenges our understanding due to differing units across dimensions.
In high dimensions, the volume of a sphere relative to its bounding cube decreases, which aligns with the concept of adding dimensions and is significant for understanding spatial relationships.
High-dimensional spaces enable near-orthogonality, a critical concept in machine learning, allowing many directions to be sufficiently orthogonal, which is essential for algorithms and data analysis.
FM radio is superior to AM radio in terms of sound quality because it is less susceptible to noise interference.- FM operates by varying frequency, whereas AM varies amplitude, making FM less affected by noise, which primarily impacts amplitude.- Edwin Howard Armstrong, the inventor of FM, anticipated that FM would reduce noise, a significant advantage over AM systems that struggle to eliminate noise without message loss.
FM radio offers superior audio fidelity compared to AM due to its higher bandwidth, with channels spaced 200 kHz apart versus AM's 9 kHz.
FM is less prone to noise interference because it encodes information through frequency variations, making it more resistant to static and amplitude-based noise.
The higher frequency band of FM avoids low-frequency noise, such as that from thunderstorms, resulting in clearer sound quality, particularly for music.
