The NIST Uncertainty Machine is a web-based software application produced by the National Institute of Standards and Technology (NIST) to evaluate the measurement uncertainty associated with a scalar or vectorial output quantity that is a known and explicit function of a set of scalar input quantities for which estimates and evaluations of measurement uncertainty are available.
With an eye towards travel agencies that could be useful for our family travel.

An orrery is a mechanical model of the Solar System that illustrates or predicts the relative positions and motions of the planets and moons, usually according to the heliocentric model.
This simulated view of our solar system runs on real data. The positions of the planets, moons and spacecraft are shown where they are right now.
Runs better in Chromium-based browser (didn't work in my Firefox).

An aggregator is only as good as the OTAs (online travel agencies) it canvasses. There are booking engines that find prices themselves (Expedia, Priceline, Hotwire). And then there are aggregators—sites that do not book tickets but instead search dozens of booking engines, airfare sites, and OTAs and compile the results in one place; you then click through to the one of your choice to make the actual purchase.
