The appointment of U Thant of Burma as the U.N.'s Acting Secretary General -- at this writing, the choice appears to be certain -- offers further proof that in politics it is more important to have no influential enemies than to have influential friends.

With the neutralists maintaining pressure for one of their own to succeed Mr. Hammarskjold, U Thant emerged as the only possible candidate unlikely to be waylaid by a veto.

U Thant of course, will hold office until the spring of 1963, when Mr. Hammarskjold's term would have come to an end.

the West may or not remain satisfied with the kind of neutralism that U Thant represents.

If Af are the projections associated with the primary decomposition of T, then each Af is a polynomial in T, and accordingly if a linear operator U commutes with T then U commutes with each of the Af, i.e., each subspace Af is invariant under U.

Near Q, both curves can be represented by analytic functions of U.

In a neighborhood of Q the difference between these functions is also a single-valued, analytic function of U.

The restrained gyro-stabilized platform with reasonable response characteristics operates with an approximate equation of motion, neglecting transient effects, as follows: Af where U is a torque applied about the output axis of the controlling gyro.

Lincoln's assassination was the first assassination of a U. S. president and sent the nation into mourning.

Lincoln has been consistently ranked by scholars and the public as one of the three greatest U. S. presidents.

In 1846, Lincoln was elected to the U. S. House of Representatives, where he served one two-year term.

Douglas ' provision, which Lincoln opposed, specified settlers had the right to determine locally whether to allow slavery in new U. S. territory, rather than have such a decision restricted by the national Congress.

In late 1854, Lincoln ran as a Whig for the U. S. Senate seat from Illinois.

After the state Republican party convention nominated him for the U. S. Senate in 1858, Lincoln delivered his House Divided Speech, drawing on: " A house divided against itself cannot stand.

The stage was then set for the campaign for statewide election of the Illinois legislature which would, in turn, select Lincoln or Douglas as its U. S. senator.

Douglas said that Lincoln was defying the authority of the U. S. Supreme Court and the Dred Scott decision.

The U. S. Navy illegally intercepted a British merchant ship the Trent on the high seas and seized two Confederate envoys ; Britain protested vehemently while the U. S. cheered.

He argued before and during his election that the eventual extinction of slavery would result from preventing its expansion into new U. S. territory.
