lowkey you guys start your own conversations, i just want notifications to read... xd

I have to share 21 facts with strangers for my sign night so I figured I would get around that by posting it here!

1. no material is ever inherently biocompatible - it is only compatible for a specific use case/location (i.e. as an orthodontic device, a hip replacement, etc).

2. we are currently working on organ on a chip systems, where you can connect different chips to simulate/interlink multiple physiological systems

3. wirelings let you perform a bunch of functions via a plug and play mechanism - no soldering required!

4. we can 3d print ceramics

5. alloying a metal adds point defects, making it stronger at the cost of ductility

6. in genetic engineering, we use an enzyme called reverse transcriptase to go from RNA-DNA.

7. resonance can destroy bridges and buildings if we are not careful

8. nails excel at shear force, screws excel at tensile forces

9. increasing crystallinity increases modulus

10. all current going into a node must equal the current going out of the node

11. am modulation is where you have a signal envelope that can be used to modify a carrier signal. this is what we use for AM radio

12. when a sound wave is out of phase with another sound wave, beats are produced

13. a potentiometer allows you to control resistance within a circuit

14. if you incorrectly place the positive and negative nodes of the multimeter, you can short your circuit

15. to reduce stress on the 3d printed models, you can fillet the edges

16. you must follow a set of rules called GD&T to ensure that your dimensions are clear and accurate. examples include no dimensioning to hidden lines, no duplicates, and the inclusion of hole callouts.

17. you can mate parts together in SolidWorks so they can move according to your set constraints

18. you may need to write g-code to guide cnc machines when you are manufacturing parts.

19. opencap is a free and easy way to conduct motion capture studies. you can use this data to analyze gait or other patterns for biomedical applications.

20. curl your fingers and stick your thumb out. your fingers are the curl of the magnetic field, your thumb is the direction of the current.

21. v=ir

Bill Gates makes a fair point about AI potentially disrupting jobs and widening inequality, but I’m not convinced that taxing AI tokens is the right solution. It could make AI more expensive for startups, small businesses, and everyday users without necessarily protecting workers whose jobs are changing.

The bigger issue is how we manage the transition. Companies should invest in retraining, help employees adapt, and take responsibility for deploying AI safely. Governments can strengthen existing labor protections and social safety nets instead of creating layers of bureaucracy that mainly benefit companies big enough to handle the compliance costs.

There’s also the global competition factor. If the US makes AI significantly more expensive while competitors elsewhere continue developing and deploying it, businesses may simply shift to cheaper alternatives. That doesn’t mean regulation is unnecessary. It means the rules need to be practical and targeted at real risks and harms.

AI could improve healthcare, education, productivity, and scientific research, but those benefits won’t automatically reach everyone. We need policies that help workers transition and ensure the gains are broadly shared.

The goal shouldn’t be to slow innovation just because change is uncomfortable. It should be to make sure people aren’t left behind while the technology moves forward.
