</div></div></div><div class="field field-name-field-body field-type-text-long field-label-hidden"><div class="field-items"><div class="field-item even"><p>School of Mathematics Professor <a href="https://people.math.gatech.edu/~ghomi/">Mohammad Ghomi</a> and <a href="https://mathematics.jhu.edu/directory/joel-spruck/" rel="nofollow">Joel Spruck</a> of Johns Hopkins University this week <a href="https://arxiv.org/abs/1908.09814" rel="nofollow">posted in ArXiv</a> their proposed solution to the Cartan-Hadamard Conjecture, a long-standing problem in Analysis and Geometry, which is concerned with a generalization of the classical <a href="https://en.wikipedia.org/wiki/Isoperimetric_inequality" rel="nofollow">isoperimetric inequality</a>.</p>
<p>In Euclidean space, to enclose a given volume with the smallest possible perimeter, one should use a ball. Comparing the volume of the ball to its surface area yields a numerical measure of the efficiency of this enclosure which lies at the base of a range of important inequalities in mathematics and physics. There are more general models of space than the Euclidean framework, however. Some of the most natural and attractive ones are those with nonpositive curvature, which are known as Cartan-Hadamard manifolds. The simplest examples of Cartan-Hadamard manifolds include potato chips and coral reefs. Cartan-Hadamard manifolds aim to include more area in less space, like waves of a petunia flower.</p>
<p>The exploration of the isoperimetric inequality in Cartan-Hadamard manifolds can be traced back to work of Andre Weil, a student of Hadamard at the time, who addressed the two dimensional case in 1926. Around fifty years later, Thierry Aubin, Misha Gromov, Yuri Burago and Victor Zalgaller conjectured that, in all dimensions, Cartan-Hadamard manifolds should satisfy the same isoperimetric inequality as in Euclidean space. Prior to Ghomi and Spruck’s work, the only other known cases where in dimensions 3 and 4, due to Bruce Kleiner in 1992 and Chris Croke in 1984 respectively. </p>
<p>The proposed proof settles the conjecture in all dimensions. As a result several other well-known inequalities in Analysis and Mathematical Physics may now be generalized to spaces of nonpositive curvature as well. These include the Sobolev inequalities, which are fundamental in theory of functions, and the Faber-Krahn inequality, which dates back to a conjecture of Lord Rayleigh in 1877 concerning the spectrum of the Laplace operator, or the theory of sound. </p>
<p>Mohammad Ghomi completed his Ph.D. in 1998 at Johns Hopkins University under the direction of Spruck. As a geometer, Ghomi works on <a href="http://people.math.gatech.edu/~ghomi/Papers/op.pdf">classical problems</a> involving curves and surfaces in Euclidean space and, more generally, Riemannian submanifolds. He is interested in all aspects of mathematics that touch upon these objects, ranging from differential geometry and topology to real algebraic geometry and combinatorics.</p>

</div></div></div><div class="field field-name-field-body field-type-text-long field-label-hidden"><div class="field-items"><div class="field-item even"><p>College of Sciences faculty raised a historic amount of external research funding in fiscal year 2019. At $70.5 million, the FY2019 total continues the College’s steady gains in external grants for the past several years. The ability to attract research funds bodes well for the College’s research productivity, ability to train students, and opportunities for new discoveries in fundamental science for many years to come, says <a href="https://cos.gatech.edu/leadership">Associate Dean for Research Julia Kubanek</a>.</p>
<p>Scientific research to discover new knowledge and solve problems is hard and costs money, says <a href="https://www.chemistry.gatech.edu/people/finn/m.g.">M.G. Finn</a>, professor and chair in the School of Chemistry and Biochemistry. Results are not guaranteed. “How do we support an endeavor that has many more ‘failures’ than successes?”</p>
<p>External funding is essential. “It helps connect our faculty to the most important fundamental and applied problems among a limitless set of possible projects,” Finn says. “It also provides the resources to give our students the chance to fail repeatedly, and thereby learn how to succeed. Increasing funding is a good sign that we are selecting good topics to research, failing in productive ways, and ultimately succeeding in uncovering new knowledge and valued applications of that knowledge.” </p>
<p>The College of Sciences’ success can be attributed to two other factors. Faculty are applying for grant dollars at increasing rates, says Kubanek, who is also a professor in the Schools of Biological Sciences and of Chemistry and Biochemistry. And “we are continuing to submit to federal funding agencies high-quality proposals, despite the increase in reporting, compliance, and other requirements, thanks to staff who support principal investigators in preparing proposals and managing grants.”</p>
<p> “External funding is essential for our mission of providing students with an outstanding training and fostering a vibrant environment of transformative research,” says <a href="https://www.physics.gatech.edu/user/pablo-laguna">Pablo Laguna,</a> professor and chair in the School of Physics. The school saw a dramatic rise in external funding, almost doubling from FY2018. “The rise in external funding in FY2019 reflects the commitment of my colleagues to ensure that we accomplish this mission. New awards in the areas of Astrophysics, Physics of Living Systems, and Atomic and Molecular and Optical Physics were largely responsible for this increase.”</p>
<p>The awards support a wide range of research activities, from exploration of Jupiter’s moon Europa (<a href="https://www.eas.gatech.edu/people/schmidt-dr-britney">Britney Schmidt</a>, School of Earth and Atmospheric Sciences), to algebraic geometry and extremal combinatorics (<a href="https://sites.google.com/site/grrigg/" rel="nofollow">Greg Blekherman</a>, School of Mathematics), to wearable hydration technologies (<a href="https://biosci.gatech.edu/people/mindy-millard-stafford">Mindy Millard-Stafford</a>, School of Biological Sciences).</p>
<p>Support came mostly from public sources. For example, <a href="https://www.physics.gatech.edu/user/nepomuk-otte">Nepomuk Otte</a> received NASA funding for the project “Development of a Photon Detection Module for the Detection of Cosmogenic Neutrinos.” The project aims to develop instrumentation to detect ultra-relativistic neutrinos of astrophysical origin.</p>
<p> Neutrinos are elementary particles that help us understand the origin and composition of the highest energy cosmic rays. Cosmic rays are charged particles, which bombard the Earth from all directions. “Where they come from, what their composition is, and how they acquire their relativistic energies is a century-old mystery,” says Otte, who is an associate professor in the School of Physics. “One way to find out is by measuring neutrinos, which are produced by these cosmic rays. With the instrumentation developed in this project it will be possible to build new experiments that have the sensitivity to detect ultra-relativisitic neutrinos for the first time.” </p>
<p>Meanwhile, <a href="https://www.chemistry.gatech.edu/people/agarwal/vinayak">Vinayak Agarwal</a> received ongoing National Institutes of Health funding for the project “Understanding Natural Production of Polybrominated Toxins and Pollutants.” Molecules bearing several bromine atoms produced naturally in marine ecosystems can harm human health and the environment. “We do not know how these molecules are made, nor the identities of their producers,” says Agarwal, who is an assistant professor in the Schools of Chemistry and Biochemistry and of Biological Sciences. This research aims to bridge these knowledge gaps and could affect public health policies to mitigate human exposure to natural harmful compounds.</p>

</div></div></div><div class="field field-name-field-body field-type-text-long field-label-hidden"><div class="field-items"><div class="field-item even"><p>College of Sciences faculty raised a historic amount of external research funding in fiscal year 2019. At $70.5 million, the FY2019 total continues the College’s steady gains in external grants for the past several years. The ability to attract research funds bodes well for the College’s research productivity, ability to train students, and opportunities for new discoveries in fundamental science for many years to come, says <a href="https://cos.gatech.edu/leadership">Associate Dean for Research Julia Kubanek</a>.</p>
<p>Scientific research to discover new knowledge and solve problems is hard and costs money, says <a href="https://www.chemistry.gatech.edu/people/finn/m.g.">M.G. Finn</a>, professor and chair in the School of Chemistry and Biochemistry. Results are not guaranteed. “How do we support an endeavor that has many more ‘failures’ than successes?”</p>
<p>External funding is essential. “It helps connect our faculty to the most important fundamental and applied problems among a limitless set of possible projects,” Finn says. “It also provides the resources to give our students the chance to fail repeatedly, and thereby learn how to succeed. Increasing funding is a good sign that we are selecting good topics to research, failing in productive ways, and ultimately succeeding in uncovering new knowledge and valued applications of that knowledge.” </p>
<p>The College of Sciences’ success can be attributed to two other factors. Faculty are applying for grant dollars at increasing rates, says Kubanek, who is also a professor in the Schools of Biological Sciences and of Chemistry and Biochemistry. And “we are continuing to submit to federal funding agencies high-quality proposals, despite the increase in reporting, compliance, and other requirements, thanks to staff who support principal investigators in preparing proposals and managing grants.”</p>
<p> “External funding is essential for our mission of providing students with an outstanding training and fostering a vibrant environment of transformative research,” says <a href="https://www.physics.gatech.edu/user/pablo-laguna">Pablo Laguna,</a> professor and chair in the School of Physics. The school saw a dramatic rise in external funding, almost doubling from FY2018. “The rise in external funding in FY2019 reflects the commitment of my colleagues to ensure that we accomplish this mission. New awards in the areas of Astrophysics, Physics of Living Systems, and Atomic and Molecular and Optical Physics were largely responsible for this increase.”</p>
<p>The awards support a wide range of research activities, from exploration of Jupiter’s moon Europa (<a href="https://www.eas.gatech.edu/people/schmidt-dr-britney">Britney Schmidt</a>, School of Earth and Atmospheric Sciences), to algebraic geometry and extremal combinatorics (<a href="https://sites.google.com/site/grrigg/" rel="nofollow">Greg Blekherman</a>, School of Mathematics), to wearable hydration technologies (<a href="https://biosci.gatech.edu/people/mindy-millard-stafford">Mindy Millard-Stafford</a>, School of Biological Sciences).</p>
<p>Support came mostly from public sources. For example, <a href="https://www.physics.gatech.edu/user/nepomuk-otte">Nepomuk Otte</a> received NASA funding for the project “Development of a Photon Detection Module for the Detection of Cosmogenic Neutrinos.” The project aims to develop instrumentation to detect ultra-relativistic neutrinos of astrophysical origin.</p>

<blockquote><p>Ultimately, though, where you are sat on a flight can dictate what lurgies you end up with. <a href="https://people.math.gatech.edu/~weiss/">Howard Weiss</a>, a biomathematician at the Georgia Institute of Technology, modelled behaviour on flights and calculated the risks of becoming ill with airborne diseases. “Direct transmission of diseases such as flu is very unlikely beyond passengers seated about a metre away from the infected passenger,” says Weiss. “For flu, I think the worst case was overall there would be two additional infections in the entire economy cabin.”</p>
<p>Weiss and his team also took swabs from planes. “What we found was the bacteria that you find in an airplane looks a lot like in your home or office. If you are not immune-compromised, then as long as you keep your hands away from your face, you’re probably going to be fine. People have this impression that airplanes are like sewers, but we’ve shown that’s not the case.”</p>

<p>For those people, as well as those born after July 20, 1969, the 50th anniversary of the <a href="https://www.kennedyspacecenter.com/launches-and-events/events-calendar/2019/july/apollo-11-moon-landing" rel="nofollow">Apollo 11 Moon landing</a> is a chance to loudly celebrate the advances in science and technology created by the space program.</p>
<p>“The money was well spent, and we should do it again,” says <a href="https://www.ajc.com/lifestyles/cobb-man-remembers-his-role-historic-apollo-moon-landing/cb2KTACCz9DZgd25nv17dL/" rel="nofollow">Bob McDonald</a>, a Georgia Tech alumnus who, as a young engineer for a NASA contractor, worked on the engines in that Saturn V rocket that lifted astronauts Neil Armstrong, Buzz Aldrin, and Michael Collins into space on July 16,1969.</p>
<p>Armstrong and Aldrin piloted their lunar lander to the Moon’s surface on July 20, 1969. Later that day, Armstrong became the first man on the Moon. As he stepped off the lander, he told an estimated TV audience of a half-billion, “That’s one small step for man, one giant leap for mankind.”</p>
<p>Those memories will flood back on Saturday, July 20, 50 years to the day since that moment in history. We asked some Georgia Tech College of Sciences researchers – and an alumnus with a special connection to that day – their thoughts on how Apollo 11 and the space program impacted the cause of science and technology in the U.S.</p>
<h4><strong>Bob McDonald</strong></h4>
<p><em>He’s 83 years old and enrolled in the <a href="https://www.analytics.gatech.edu/">Online Master of Science in Analytics</a> program, making him Georgia Tech’s oldest graduate student, according to <a href="https://pe.gatech.edu/">Georgia Tech Professional Education</a>. This will be his fourth degree from Tech. He already has a B.S. in <a href="http://www.chbe.gatech.edu/">Chemical Engineering </a>(’57) and a Masters (’61) and Ph.D. (’66) in <a href="http://nremp.gatech.edu/">Nuclear Engineering</a>. McDonald had a unique front-row seat for the Apollo program. </em></p>
<p> “I was a brand new engineer working for <a href="https://www.rocket.com/" rel="nofollow">Rocketdyne</a>, who had a contract to manufacture the J2 engines for the Saturn rocket. There were five J2s on the Saturn second stage to get into Earth orbit. A single J2 powered the third stage to the Moon and back. </p>
<p>“The J2 was a new, liquid hydrogen- and liquid oxygen-fueled engine. To prevent the rocket exhaust from melting the engine, liquid hydrogen was pumped through small tubes down to the end of the engine bell, then back up to the combustion chamber for burning. My job was to do the heat transfer and flow calculations for the hydrogen in those tubes to make sure temperatures would be within design limits. This was prior to engine testing when the temperatures could be measured directly. When the engine was tested and performed correctly, my job was finished.</p>
<p>“One interesting thing about the [Apollo] project was that we already knew all the science and math needed for success. We knew where the Moon was, how far we had to travel, how long it would take, and how much energy was required. What we did not have was any of the hardware, the machinery, or equipment necessary to make the trip. Developing, testing, and learning to use the necessary equipment was a job for the engineers. Engineering and science are like one pair of gloves, and both benefitted. At the end of the project the United States was stronger, more prosperous, and wiser than when it began. The money was well spent, and we should do it again.”</p>
<blockquote><p><em><strong>"The money was well spent, and we should do it again."</strong></em></p>
</blockquote>
<h4><strong>Jennifer Glass</strong></h4>
<p><em>An associate professor in the <a href="http://eas.gatech.edu/">School of Earth and Atmospheric Sciences</a>, <a href="http://www.eas.gatech.edu/people/glass-dr-jennifer">Glass</a> was a <a href="https://astrobiology.nasa.gov/" rel="nofollow">NASA Astrobiology</a> Postdoctoral Fellow at the <a href="https://www.caltech.edu/" rel="nofollow">California Institute of Technology</a> from 2011 to 2013. Her research area is biogeochemistry.</em></p>
<p>“The Moon gives the Earth tides and stabilizes our climate by preventing the planet’s tilt from changing more than a few degrees. But until the Apollo program, we didn’t know exactly how old the Moon was or what it was made of. A major achievement of the Apollo program was reconstruction of the timeline of the Moon's formation. These data came from measurements of the isotopic composition of rock samples that Apollo 11 astronauts collected on the Moon 50 years ago this month. One of these scientists was my academic grandfather (my Ph.D. advisor’s Ph.D. advisor), the late <a href="https://www.caltech.edu/about/news/remembering-gerald-wasserburg-51175" rel="nofollow">Gerald Wasserburg</a>, who ran a lab at Caltech called the ‘Lunatic Asylum’. </p>
<p>“Perhaps the most important emblem of the Apollo program was the iconic photo of Earth rising over the lunar horizon, captured by Apollo 8 astronaut <a href="https://en.wikipedia.org/wiki/William_Anders" rel="nofollow">William Anders</a>. The <a href="http://100photos.time.com/photos/nasa-earthrise-apollo-8" rel="nofollow">Earthrise photo</a> profoundly changed human consciousness. That image made people realize how special our own planet is – a pale blue dot against the vastness of space. It ushered in the environmental awareness of the 1970s.”</p>
<h4><strong>Rafael de la Llave</strong></h4>
<p><em>A professor in the School of Mathematics, <a href="http://people.math.gatech.edu/~rll6/">de la Llave</a> researches dynamical systems, including the study of orbits. In 2015, de la Llave and two other scientists received a <a href="https://www.news.gatech.edu/2018/01/12/mathematics-fuels-space-exploration">$100,000 NASA grant</a> to research how math could help make space travel less costly and more efficient. </em></p>
<p>“When the Moon landing happened, I was a kid in Spain. Like everybody else in the world, I was deeply moved and full of admiration.</p>
<p>"The Moon landing changed the vision we had of our planet and of our species. It was technology impacting on religion and philosophy, not just on everyday life, from GPS, and mobile cameras to wireless technology.</p>
<p>The Moon landing also changed politics; it showed that big democratic and united organizations, where ideas percolate up and down, are more efficient than rigid ones. It was an accomplishment that made the whole world reflect.”</p>
<blockquote><p><em><strong>"The Moon landing...showed that democratic and united organizations, where ideas percolate up and down, are more efficient than rigid ones."</strong></em></p>

<h4><strong>John Wise</strong></h4>
<p><em><a href="https://www.physics.gatech.edu/user/john-wise">Wise </a>is the Dunn Family Associate Professor in the <a href="https://cra.gatech.edu/">Center for Relativistic Astrophysics </a>in the <a href="https://www.physics.gatech.edu/">School of Physics</a>. Wise uses supercomputers to create simulations of the Big Bang, along with the birth of stars and the lifespan of black holes. </em></p>
<p>“The Apollo program accelerated rocket technology and space science for years to come, not only in the U.S. but around the globe. The feats achieved by the whole team inspired a generation of young people into STEM fields, fascinated by the depths of space. The advancements in rockets led to many space telescopes and planetary probes in decades to come.</p>
<p>“The discoveries by NASA telescopes and probes partly motivated me to pursue astrophysics as a career. As an 80's kid, I lingered over pictures of the gas giant planets sent back by the Voyager spacecraft.</p>
<p>“A decade later, the<a href="https://hubblesite.org/" rel="nofollow"> Hubble Space Telescope </a>gave us images of galaxies across the universe. Many other scientists have told me that they had similar formative memories of NASA missions. Without the Apollo program pushing the limits of humankind, these space science missions might have not been possible in the 20th century.”</p>

<blockquote><p>Ultimately, though, where you are sat on a flight can dictate what lurgies you end up with. <a href="https://people.math.gatech.edu/~weiss/">Howard Weiss</a>, a biomathematician at the Georgia Institute of Technology, modelled behaviour on flights and calculated the risks of becoming ill with airborne diseases. “Direct transmission of diseases such as flu is very unlikely beyond passengers seated about a metre away from the infected passenger,” says Weiss. “For flu, I think the worst case was overall there would be two additional infections in the entire economy cabin.”</p>
<p>Weiss and his team also took swabs from planes. “What we found was the bacteria that you find in an airplane looks a lot like in your home or office. If you are not immune-compromised, then as long as you keep your hands away from your face, you’re probably going to be fine. People have this impression that airplanes are like sewers, but we’ve shown that’s not the case.”</p>
