Here is another way to think about that story: DOT and their proven, reliable contractor had experience with a certain method of rehabbing the joints between concrete slabs. A new technique was tried, and the first few attempts were not don

The usual solution to this is gentle curves and conical wheel shapes Standard wheels are conical. You can optimize the wheel and track profiles for curves, but that may affect the wheel behavior on tangent track where "hunting"

There should be targeted interventions to address them imo. They are targeted. The issue is that in the end, it's a geometry problem -- in curves, one wheel wants to move faster than the other, which results in one wheel flange being

Many people choose earbuds that are not isolating intentionally because they want to be aware of their surroundings and thus don't increase the volume to compensate. That might be true, but I'd bet good money most people chose n

Perhaps things changed in the 20 years since I graduated, but based on the college aid packages offered to me, it was less expensive for me to go to MIT than it was to go to UMass Amherst.

It is possible to tackle more than one issue at a time. Also realize that noise is often a measure of inefficiency - for instance, one of the ways to make trains quieter is to keep wheels and rails smooth. That has the added benefit of exte

The technology is ready - EVs - but the ramp up is taking too long. Above about 30-35 mph, EV's aren't much quieter than ICE cars, the contribution from road/tire noise starts to dominate for both types of autos above those

The slide shows that NSA was collecting data from those providers, not that the providers willingly supplied the data. When someone steals from you, the victim didn't "knowingly" give the property away.
