Thixotropy is a time-dependent shear thinning property. Certain gels or fluids that are thick or viscous under static conditions will flow (become thinner, less viscous) over time when shaken, agitated, shear-stressed , or otherwise stressed ( time-dependent viscosity ). They then take a fixed time to return to a more ... | https://en.wikipedia.org/wiki/Thixotropy |
In chemistry , a thiyl radical has the formula RS, sometimes written RS • to emphasize that they are free radicals . R is typically an alkyl or aryl substituent. Because S–H bonds are about 20% weaker than C–H bonds, thiyl radicals are relatively easily generated from thiols RSH. [ 1 ] Thiyl radicals are intermediate... | https://en.wikipedia.org/wiki/Thiyl_radical |
Tho-Radia was a French pharmaceutical company making cosmetics between 1932 and 1968. Tho-Radia-branded creams, toothpastes and soaps were notable for containing radium and thorium until 1937, as a scheme to exploit popular interest for radium after it was discovered by Pierre and Marie Curie , in a fad of radioactive ... | https://en.wikipedia.org/wiki/Tho-Radia |
Tholins (after the Greek θολός ( tholós ) "hazy" or "muddy"; [ 1 ] from the ancient Greek word meaning "sepia ink") are a wide variety of organic compounds formed by solar ultraviolet or cosmic ray irradiation of simple carbon-containing compounds such as carbon dioxide ( CO 2 ), methane ( CH 4 ) or ethane ( C 2 H 6 ),... | https://en.wikipedia.org/wiki/Tholin |
In mathematics, especially in differential topology , Thom's first isotopy lemma states: given a smooth map f : M → N {\displaystyle f:M\to N} between smooth manifolds and S ⊂ M {\displaystyle S\subset M} a closed Whitney stratified subset , if f | S {\displaystyle f|_{S}} is proper and f | A {\displaystyle f|_{A}} is ... | https://en.wikipedia.org/wiki/Thom's_first_isotopy_lemma |
In mathematics, especially in differential topology , Thom's second isotopy lemma is a family version of Thom's first isotopy lemma ; i.e., it states a family of maps between Whitney stratified spaces is locally trivial when it is a Thom mapping . [ 1 ] Like the first isotopy lemma, the lemma was introduced by René Tho... | https://en.wikipedia.org/wiki/Thom's_second_isotopy_lemma |
In mathematics , a smooth algebraic curve C {\displaystyle C} in the complex projective plane , of degree d {\displaystyle d} , has genus given by the genus–degree formula

In mathematics , Thomae's formula is a formula introduced by Carl Johannes Thomae ( 1870 ) relating theta constants to the branch points of a hyperelliptic curve ( Mumford 1984 , section 8).
In 1824, the Abel–Ruffini theorem established that polynomial equations of a degree of five or higher could have no solutions in... | https://en.wikipedia.org/wiki/Thomae's_formula |
Thomae's function is a real -valued function of a real variable that can be defined as: [ 1 ] : 531 f ( x ) = { 1 q if x = p q ( x is rational), with p ∈ Z and q ∈ N coprime 0 if x is irrational. {\displaystyle f(x)={\begin{cases}{\frac {1}{q}}&{\text{if }}x={\tfrac {p}{q}}\quad (x{\text{ is rational), with }}p\in \mat... | https://en.wikipedia.org/wiki/Thomae's_function |
In the dynamical systems theory , Thomas' cyclically symmetric attractor is a 3D strange attractor originally proposed by René Thomas . [ 1 ] It has a simple form which is cyclically symmetric in the x, y, and z variables and can be viewed as the trajectory of a frictionally dampened particle moving in a 3D lattice of ... | https://en.wikipedia.org/wiki/Thomas'_cyclically_symmetric_attractor |
The Thomas A.
