U.S. government takes 10% stake in Intel: Axios' Marc Caputo on how the deal came about
CNBC Television· 2025-08-25 11:31
President Trump announcing the government has taken a 10% stake in Intel. Shares of the chipmaker have soared nearly 30% since the start of the month. Joining us right now is Mark Coopo. He's Access's senior political reporter. Uh we've all been uh trying to make sense of this, trying to understand if there's a a bigger implication or if you think that we should think about this more in a oneoffish way. What do you say? Uh, I would think you would think about it sort of like AIG, which was bailed out in the ...

Core Message - Modern technology relies heavily on artificial crystal systems, impacting various fields like electronics, illumination, and communication [1][2][3] - Crystals are essential for computers, mobile phones, navigation systems, military drones, the internet, artificial intelligence, and social media [1] Historical Context & Scientific Breakthroughs - Historically, crystals were used for jewelry and by fortune tellers, but lacked technical significance beyond salt [6][7] - In the mid-19th century, scientists began describing crystal geometry mathematically, identifying 14 different unit cells [9] - Max von Laue's X-ray diffraction in 1912 allowed scientists to visualize the arrangement of atoms within crystals, revealing their symmetrical structure [12][13] - A cubic centimeter of crystal contains approximately 10^22 atoms arranged regularly [13] Technological Applications & Impact - Semiconductor crystals are used in modern LED lamps for light generation and in lasers for cutting, welding, drilling, and data transmission [3] - Quartz crystals oscillate over 32,000 times per second in watches for accurate timekeeping [4] - Piezoelectric crystals generate ultrasound for medical diagnostics, and liquid crystals are used in mobile phone and computer screens [5] - Silicon and germanium crystals are used to construct small electrical devices like diodes and transistors, crucial for radar systems and modern electronics [17][19] Crystal Properties & Artificial Growth - Crystals exhibit regularity, smooth surfaces, sharp edges, transparency, and brilliance due to their ordered atomic structure [8] - The properties of crystals can be altered by introducing foreign atoms into the crystal lattice; for example, iron atoms in quartz create amethyst [15] - Understanding the conditions necessary for artificial crystal growth, such as temperature, pressure, and concentration, is crucial for technological applications [16][17]
