Julian Voss-Andreae (born 15 August 1970) is a German sculptor living and working in the U.S.
Voss-Andreae's full first name is Johann Julian, in honor of his ancestor, German pastor Johann Valentin Andreae. According to an interview with the artist, Voss-Andreae attended a Rudolf Steiner school in Germany from grades 9 to 13. [1]
Voss-Andreae was born in Hamburg, Germany (formerly West Germany) and started out as a painter. [2] He later studied experimental physics at the universities of Berlin, Edinburgh and Vienna. Voss-Andreae pursued his graduate research in quantum physics in Anton Zeilinger's research group, participating in an experiment demonstrating quantum behavior for the largest objects to date. [3] He moved to the U.S. in 2000 and graduated from the Pacific Northwest College of Art in 2004.
Voss-Andreae's work is heavily influenced by his background in science. His work includes protein sculptures, [4] such as Angel of the West (2008), [1] [5] a large-scale outdoor sculpture for the Scripps Research Institute in Jupiter, Florida portraying the human antibody molecule, a sculpture for Nobel laureate Roderick MacKinnon based on the ion channel structure, [6] and the quantum physics-inspired Quantum Man (2006). [7] [8]
Recent work includes an exhibition at the American Center for Physics displaying a series of sculptures inspired by concepts from quantum physics. [9]
In 2020 he was awarded the Waltrude-and-Friedrich-Liebau-prize for the Promotion of Interdisciplinarity in Crystallography by the German Crystallographic Society. [10]
An alpha helix is a sequence of amino acids in a protein that are twisted into a coil.
Quantum chemistry, also called molecular quantum mechanics, is a branch of physical chemistry focused on the application of quantum mechanics to chemical systems, particularly towards the quantum-mechanical calculation of electronic contributions to physical and chemical properties of molecules, materials, and solutions at the atomic level. These calculations include systematically applied approximations intended to make calculations computationally feasible while still capturing as much information about important contributions to the computed wave functions as well as to observable properties such as structures, spectra, and thermodynamic properties. Quantum chemistry is also concerned with the computation of quantum effects on molecular dynamics and chemical kinetics.
X-ray crystallography is the experimental science of determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract in specific directions. By measuring the angles and intensities of the X-ray diffraction, a crystallographer can produce a three-dimensional picture of the density of electrons within the crystal and the positions of the atoms, as well as their chemical bonds, crystallographic disorder, and other information.
Linus Carl Pauling was an American chemist, biochemist, chemical engineer, peace activist, author, and educator. He published more than 1,200 papers and books, of which about 850 dealt with scientific topics. New Scientist called him one of the 20 greatest scientists of all time. For his scientific work, Pauling was awarded the Nobel Prize in Chemistry in 1954. For his peace activism, he was awarded the Nobel Peace Prize in 1962. He is one of five people to have won more than one Nobel Prize. Of these, he is the only person to have been awarded two unshared Nobel Prizes, and one of two people to be awarded Nobel Prizes in different fields, the other being Marie Curie.
The green fluorescent protein (GFP) is a protein that exhibits green fluorescence when exposed to light in the blue to ultraviolet range. The label GFP traditionally refers to the protein first isolated from the jellyfish Aequorea victoria and is sometimes called avGFP. However, GFPs have been found in other organisms including corals, sea anemones, zoanithids, copepods and lancelets.
Anton Zeilinger is an Austrian quantum physicist and Nobel laureate in physics of 2022. Zeilinger is professor of physics emeritus at the University of Vienna and senior scientist at the Institute for Quantum Optics and Quantum Information of the Austrian Academy of Sciences. Most of his research concerns the fundamental aspects and applications of quantum entanglement.
In physics, complementarity is a conceptual aspect of quantum mechanics that Niels Bohr regarded as an essential feature of the theory. The complementarity principle holds that certain pairs of complementary properties cannot all be observed or measured simultaneously. For example, position and momentum or wave and particle properties. In contemporary terms, complementarity encompasses both the uncertainty principle and wave-particle duality.
Arthur Brouhard Robinson is an American biochemist, conservative activist, prominent climate change denier, and politician serving as Oregon State Senator from the 2nd District since 2021. He was the five-time Republican nominee for the United States House of Representatives for Oregon's 4th congressional district.
"Molecular Structure of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid" was the first article published to describe the discovery of the double helix structure of DNA, using X-ray diffraction and the mathematics of a helix transform. It was published by Francis Crick and James D. Watson in the scientific journal Nature on pages 737–738 of its 171st volume.
Herman Russell Branson was an American physicist, chemist, best known for his research on the alpha helix protein structure, and was also the president of two colleges. He received a fellowship from the Rosenwald Foundation.
Martin Karplus is an Austrian and American theoretical chemist. He is the Director of the Biophysical Chemistry Laboratory, a joint laboratory between the French National Center for Scientific Research and the University of Strasbourg, France. He is also the Theodore William Richards Professor of Chemistry, emeritus at Harvard University. Karplus received the 2013 Nobel Prize in Chemistry, together with Michael Levitt and Arieh Warshel, for "the development of multiscale models for complex chemical systems".
Molecular graphics is the discipline and philosophy of studying molecules and their properties through graphical representation. IUPAC limits the definition to representations on a "graphical display device". Ever since Dalton's atoms and Kekulé's benzene, there has been a rich history of hand-drawn atoms and molecules, and these representations have had an important influence on modern molecular graphics.
In chemistry, the history of molecular theory traces the origins of the concept or idea of the existence of strong chemical bonds between two or more atoms.
Quantum Man is a modern sculpture created by Julian Voss-Andreae, which is located in the city of Moses Lake, Washington.
"Sickle Cell Anemia, a Molecular Disease" is a 1949 scientific paper by Linus Pauling, Harvey A. Itano, Seymour J. Singer and Ibert C. Wells that established sickle-cell anemia as a genetic disease in which affected individuals have a different form of the metalloprotein hemoglobin in their blood. The paper, published in the November 25, 1949 issue of Science, reports a difference in electrophoretic mobility between hemoglobin from healthy individuals and those with sickle-cell anemia, with those with sickle cell trait having a mixture of the two types. The paper suggests that the difference in electrophoretic mobility is probably due to a different number of ionizable amino acid residues in the protein portion of hemoglobin, and that this change in molecular structure is responsible for the sickling process. It also reports the genetic basis for the disease, consistent with the simultaneous genealogical study by James V. Neel: those with sickle-cell anemia are homozygous for the disease gene, while heterozygous individuals exhibit the usually asymptomatic condition of sickle cell trait.
Angel of the West is an outdoor sculpture in Jupiter, Florida, United States. The sculpture was made in 2008 by German sculptor Julian Voss-Andreae. Referencing British sculptor Antony Gormley's monumental 1998 piece Angel of the North it was created based on an antibody structure published by E. Padlan for the Florida campus of the Scripps Research Institute. The antibody is placed into a ring referencing Leonardo da Vinci's Vitruvian Man highlighting the similar proportions of the antibody and the human body.
In physics and the philosophy of physics, quantum Bayesianism is a collection of related approaches to the interpretation of quantum mechanics, the most prominent of which is QBism. QBism is an interpretation that takes an agent's actions and experiences as the central concerns of the theory. QBism deals with common questions in the interpretation of quantum theory about the nature of wavefunction superposition, quantum measurement, and entanglement. According to QBism, many, but not all, aspects of the quantum formalism are subjective in nature. For example, in this interpretation, a quantum state is not an element of reality—instead, it represents the degrees of belief an agent has about the possible outcomes of measurements. For this reason, some philosophers of science have deemed QBism a form of anti-realism. The originators of the interpretation disagree with this characterization, proposing instead that the theory more properly aligns with a kind of realism they call "participatory realism", wherein reality consists of more than can be captured by any putative third-person account of it.
