Ninth grade (also 9th grade or grade 9) is the ninth or tenth year of formal or compulsory education in some countries. It is generally part of middle school or secondary school depending on country. Students in ninth grade are usually 13-15 years old, but in some countries are 15–16.
The length of the academic day differs depending on the type school. Some school days go from 9:00 in the morning to 5:00 in the evening and students get a two-hour lunch break from 1:00 to 3:00 in the afternoon. Other schools start at 9:00 in the morning and end at 2:00 in the afternoon.
Following the discovery of a particle with properties consistent with the Higgs boson at CERN in 2012, [36] all fundamental particles predicted by the standard model, and no others, appear to exist; however, physics beyond the Standard Model, with theories such as supersymmetry, is an active area of research.

Gabor Forgacs was a Hungarian theoretical physicist turned bioengineer turned innovator and entrepreneur. He was educated in Hungary, where he earned a MS and a PhD in theoretical physics at the Lorand Eotvos University in Budapest, respectively, in 1972 and in 1976.
In the 1970s he was a co-inventor of quantum chromodynamics (QCD) which explains the confinement of quarks in mesons and baryons and forms a large part of the Standard Model of elementary particles and forces. Murray Gell-Mann received the 1969 Nobel Prize in Physics for his work on the theory of elementary particles.
David Jeffrey Griffiths (born December 5, 1942) is an American physicist and educator. He was on the faculty of Reed College from 1978 through 2009, becoming the Howard Vollum Professor of Science before his retirement.
Claudia de Rham (born 29 March 1978) is a British theoretical physicist of Swiss origin working at the interface of gravity, cosmology, and particle physics. She is based at Imperial College London.
Heinrich Friedrich Emil Lenz (German: [ˈeːmɪl ˈlɛnts]; also Emil Khristianovich Lenz; Russian: Эми́лий Христиа́нович Ленц; 12 February 1804 – 10 February 1865), usually cited as Emil Lenz [1] [2] or Heinrich Lenz in some countries, was an Estonian physicist who is most noted for formulating Lenz's law in electrodynamics in 1834.
