✨🇨🇳China's "Bamboo Replaces Plastic" initiative drives production of eco-friendly bags and tableware made from fast-growing bamboo. These products fully biodegrade in 4–6 months with no microplastic residue, and cut carbon footprints by up to 70% versus their plastic equivalents.
linear algebra is where mathematics starts becoming machinery.
• vectors
• matrices
• linear transformations
• determinants
• eigenvalues
• vector spaces
matrices and linear algebra by hans schneider & george Phillip barker builds the mathematical structure behind all of them.
the important shift is to stop seeing a matrix as a rectangular box of numbers.
a matrix is a transformation.
it can rotate space.
stretch it.
compress it.
project it.
change coordinates.
and once you think this way, linear algebra starts appearing everywhere:
• robot kinematics
• computer graphics
• control systems
• signal processing
• optimization
• machine learning
learn matrices deeply enough and you stop manipulating arrays of numbers.
you start manipulating spaces.
Live cleaning is a technique used to clean equipment while it's still powered on. It's used for solar panels, power lines, and other electrical and electronic devices.
A a special solvent is used.
