In What is Philosophy? the distinguished philosopher Dietrich von Hildebrand analyses the datum of knowledge itself in its different forms, from the most casual perception of some object in our naïve experience to "a priori knowledge," taken as consisting of absolutely certain insights into "necessary essences." Plato's central teaching about that kind of human knowledge which transcends the wo...

I went to the local Planned Parenthood recently, and am now on a birth control pill (I am absolutely sure I don't want or need to be pregnant at this point or ever in my life, personal choice.....

This paper discusses the current status of imaging radar systems deployed on spacecraft and airborne platforms, such as aircraft and unmanned airborne vehicles (UAVs). Imaging radar technology has advanced considerably over the last twenty years, and the user can now be fairly certain of finding a sensor ideal for a specific application. The objective of the paper is to demonstrate some of the ...

The General Medical Council advocates a broad experience in general professional training for doctors intending to be specialists and has indicated that a period in general practice would be beneficial.

Shahid Yusuf's review of the World Development Reports (WDRs) is elegant and insightful, but also wistful and nostalgic.

He is positive about the future, but I am not sure I agree; I think the problems that affl ict the WDRs have deep causes that will not soon go away. In my comments, I shall follow the same general...

We study random perturbations of quasi-periodic uniformly discrete sets in the d-dimensional euclidean space. By means Diffraction Theory, we find conditions under which a set X can be almost surely recovered from its perturbations. This extends recent periodic case result Yakir (Int Math Res Notices 1–19, 2020).

Two counterexamples, addressing questions raised in Adamczak (2019) and Poly Zheng (2019), are provided. Both counterexamples related to chaoses. Let F n = Y + Z , where the random variables belong different chaoses of uniformly bounded degree. It may be that ? a . s 0 L 2 ? E { sup | } < ? for some > yet fails converge a.s.
