Abstract:
For the American scientific enterprise, the past year has seemed awash in contradiction. On the one hand, it has produced great upheavals and losses for US science. Many universities experienced some degree of federal funding cuts for research; public, government, and private programs for building the scientific workforce were slashed or eliminated; the reimbursement of overhead costs in government grants for research (indirect costs) was threatened; and immigration for international students was curtailed. Yet for all of that, things now are better than might have been expected a year ago. Just last month, congressional budget bills for science had their funding restored from the Trump administration's original draconian cuts; legal challenges attempting to change indirect cost regulations were unsuccessful; and the National Institutes of Health (NIH) and the National Science Foundation disbursed all the funds they had appropriated in 2025 to universities and research institutions before the money expired. Both sides of this paradox are true, and it's difficult to understand the current moment of negative actions coexisting with positive headway without considering them both together.

Equivalent Couples
Two couples are considered to be equivalent if they produce the same rotational effect on a rigid body. In other words, the two couples have the same magnitude and act in the same direction, causing the same angular displacement or acceleration in the body.
For instance, consider two couples lying in the plane of the page, with one having a pair of equal...
Moment of a Couple: Problem Solving
The moment of a couple is found by multiplying the magnitude of one of the forces by the perpendicular distance between the line of action of the two forces. This creates a twisting force, which can be used to rotate an object. The moment of a couple is used to solve problems involving balanced...
