Vladimir Lobashev

Vladimir Lobashev is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Vladimir Lobashev rather than just read about it. In short: Vladimir Mikhailovich Lobashev (Russian: Владимир Михайлович Лобашёв; July 29, 1934 – August 3, 2011) was a Soviet and Russian physicist and expert in nuclear physics and particle physics. He authored over 200 papers, of which 25 were considered groundbreaking.

Key takeaways

Vladimir Lobashev belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Vladimir Lobashev to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Vladimir Lobashev from memory before moving on to harder problems.

Reference excerpt

Vladimir Mikhailovich Lobashev (Russian: Владимир Михайлович Лобашёв; July 29, 1934 – August 3, 2011) was a Soviet and Russian physicist and expert in nuclear physics and particle physics. He authored over 200 papers, of which 25 were considered groundbreaking.

Early life and education Lobashev was born in Leningrad. His father, Mikhail Yefimovich Lobashev, was a professor of physiology and genetics and head of the Department of Genetics at Leningrad State University. Vladimir Lobashev graduated high school in 1952 with a silver medal. He earned a degree in physics at Leningrad State University in 1957. He defended his graduate thesis in 1963, and his doctoral thesis on the non-conservation of spatial parity in the gamma decay of nuclei in 1968.

Career From 1957 to 1971, Lobashev worked as a laboratory assistant and as head of the Ioffe Physical-Technical Institute in Leningrad, collaborating also with the Leningrad Institute of Nuclear Physics. In 1972, Lobashev became head of the Department of Experimental Physics at the Institute for Nuclear Research in Moscow. In 1970, he was elected a corresponding member of the Academy of Sciences of the Soviet Union. He was awarded full membership in 2003.

Research Lobashev's main areas of research were in P and CP invariance, and neutron and neutrino physics. He discovered a new effect in quantum electrodynamics, the rotation of the plane of polarization of gamma rays in the medium of polarized electrons. His work on small effects of the non-conservation of spatial parity contributed to proving the universality of the weak interaction, and earned Lobashev the Lenin Prize in 1974. Lobashev found the most accurate limit then known on the electric dipole moment of the neutron, critical to the interpretation of CP violation. In experiments with polarized thermal neutrons, Lobashev demonstrated left-right asymmetry of fission neutron capture. With P.E. Spivakom, Lobashev proposed a new method for measuring the mass of the neutrino; this experiment placed a new lower limit on the mass of the electron antineutrino. Lobashev, along with physicist Rashid Djilkibaev, proposed the MELC experiment to search for lepton flavor violation, which influenced the later Mu2e experiment at Fermilab in the US. Lobashev was awarded the Order of the Red Banner of Labour in 1984, the Bruno Pontecorvo Prize in 1998, the Markov prize in 2004, and the Alexander von Humboldt Senior Researcher Award.

Worked examples

Example 1 — a first encounter with Vladimir Lobashev

Start with the simplest possible case. Write down what Vladimir Lobashev claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Vladimir Lobashev before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Vladimir Lobashev ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Vladimir Lobashev

In research: Vladimir Lobashev appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Vladimir Lobashev in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Vladimir Lobashev is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1934 births, 2011 deaths, 20th-century Russian physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Vladimir Lobashev outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
