The main problem is obviously to find optimal weights of the linear antenna array elements giving radiation pattern with minimum sidelobe level (SLL) and hence ameliorating the antenna array performance.

Obviously, ρ(X) = 1 (resp. ρ(X)^G= 1) if and only if each of the sets of θ-lines, η-lines, σ-lines, τ-lines is minimal (resp. G-minimal). But we need the following lemma.

While the performance of unsupervised tagging models has been slowly improving, current state-of-the-art systems make the obviously incorrect assumption that all tokens of a given word type must share a single part-of-speech tag.

Cluster tilting subcategories are obviously functorially finite and maximal rigid[.]

The mass of this bound state is 1422 MeV and its decay width is obviously smaller than that of Λ(1405).

If A is finite abelian, then every localization η:A→H is obviously epic, hence |H|≤|A|.
[This is the only use of "epic" in this paper. It is not defined anywhere. -Ed.]

Obviously since g^{(k)} is Schwartz, we have that u^{(k)}_0 is a weakly divergence free function in L^3(R^3).

Art

#Beep

A small computer which runs a Poisson process that triggers a single beep on average once a year. A challenge is issued to post a selfie in front of the machine at the #Beep.

Destructivism

A style of installation piece wherein one or more objects are brought in and smashed. The resulting debris is the piece.

Struggle

The artist spends ten hours physically attacking the canvas with his bare hands to symbolize the struggle of painting. Only the still blank canvas is displayed.

Degrees of Abstraction

You make a drawing on some form of edible paper and eat it. You take a picture of the resulting turd.

Fingerprint Counter

A fingerprint reader is connected to an enormous digital display. If you scan your fingerprint into the machine, the number increases by one, as long as you haven't done this before.

The Wisdom of Crowds

There is a plant and a button which waters the plant. The plant will die if people don't push it enough. The plant will also die if people push it too much.

Hostage

Kidnap someone. There are no demands. Display them chained to the wall of an art museum and announce they are being held captive in service to art.

Frank

If an otherworldly spirit appeared before you - poof! - and offered to magically change the name "Mohammed" to "Frank" on every official document, would you say yes?

In a sense, this question reduces to the problem: how unethical is it to inconvenience hundreds of thousands of people because it's funny?
