RoboBlockly is a web-based robot simulation environment for learning coding and math.
 Based on Blockly, it uses a simple puzzle-piece interface to program virtual Linkbot, Lego Mindstorms NXT and EV3, as well as to draw and animate for beginners to learn robotics, coding, math, science, and art.
 Blocks in RoboBlockly can be executed in debug mode step-by-step.
 All math activities in RoboBlockly are Common Core State Standards Mathematics compliant.
Carnegie Learning, Inc. is a provider of math curricula, worktexts, and math learning software for grades 6-12 written and designed to align to a Common Core or Integrated pathway.
 Its software was created by researchers in artificial intelligence from Carnegie Mellon University, led by Herbert A. Simon.
"Manifold Destiny" is an article in "The New Yorker" written by Sylvia Nasar and David Gruber and published in the August 28, 2006 issue of the magazine.
 It claims to give a detailed account (including interviews with many mathematicians) of some of the circumstances surrounding the proof of the Poincaré conjecture, one of the most important accomplishments of 20th and 21st century mathematics, and traces the attempts by three teams of mathematicians to verify the proof given by Grigori Perelman.
"Never Ending Math Equation" is a two sided single by indie rock band Modest Mouse.
 On its B-side it features "Workin' on Leavin' the Livin'", and both of which later appeared on their "Building Nothing Out of Something" compilation album.
 The 7" was originally released as part of the Sub Pop singles club.
 Since that release, the featured song "Never Ending Math Equation" has received some mainstream success and as a result of such, Modest Mouse have frequently played the song at their live performances.
 On the inside of the sleeve there is information about the second run of the Sub Pop singles club and a subscription form from 1998.
In mathematics, the soul theorem is a theorem of Riemannian geometry that largely reduces the study of complete manifolds of non-negative sectional curvature to that of the compact case.
 Cheeger and Gromoll proved the theorem in 1972 by generalizing a 1969 result of Gromoll and Wolfgang Meyer.
 The related soul conjecture was formulated by Gromoll and Cheeger in 1972 and proved by Grigori Perelman in 1994 with an astonishingly concise proof.
Grigori Yakovlevich Perelman (Russian: Григо́рий Я́ковлевич Перельма́н ; ] ; born 13 June 1966) is a Russian mathematician.
 He made a contribution to Riemannian geometry and geometric topology.
The Gorakhnath Math (Gorakhnath Mutt) is a temple of the Nath monastic group in the Nath tradition.
 The name Gorakhnath derives from the medieval saint, Gorakhnath (c. 11th century), a famous yogi who travelled widely across India and authored a number of texts that form part of the canon of the Nath sampradaya.
 The Nath tradition was founded by guru Matsyendranath.
This math is situated in Gorakhpur, Uttar Pradesh within a large premises.The temple performs various cultural and social activities and serves as the cultural hub of the city.
Askold Georgievich Khovanskii (Russian: Аскольд Георгиевич Хованский ; born 3 June 1947, Moscow) is a Russian and Canadian mathematician currently a professor of mathematics at the University of Toronto, Canada.
 His areas of research are algebraic geometry, commutative algebra, singularity theory, differential geometry and differential equations. His research is in the development of the theory of toric varieties and Newton polyhedra in algebraic geometry.
 He is also the inventor of the theory of fewnomials.
Irwin Mark Freedberg, MD (born c. 1933, Brookline, Massachusetts; died July 17, 2005, New York City) was an American dermatologist.
 He taught dermatology at Harvard Medical School, was Director of the Department of Dermatology at Johns Hopkins, was the first chief of dermatology at Beth Israel Hospital, and was the George Miller MacKee Professor and Chairman of the Ronald O. Perelman Department of dermatology at the New York University Medical Center.
 He studied the protein keratin (the main component of hair, nails, and skin) and keratinocytes (the most common cells in the epidermis).
Problems, Problems, Problems is a series of educational mathematics textbooks ranging from grade 7-12.
 The math questions are from previous math contests held by the Centre for Education in Mathematics and Computing at the University of Waterloo.
 The series is a resource to complement the Canadian high school curriculum and for self-development, although it is also used to study for the CEMC Math Contests.
 Each combined grade level has several book volumes.
 Each book contains around 300 questions, and is categorized into various sections.
 Each question has a reference number in the form "year-contest-question number".

Question: What form of math does Grigori Perelman and Askold Khovanskii have in common?
Answer: geometry
