Chemistry is the study of matter and the ways in which different forms of matter combine with each other

Chemistry is the study of matter. Our understanding of chemical processes thus depends on our ability to acquire accurate information about matter. Often, this information is quantitative, in the form of measurements. In this lab, you will be introduced to some common measuring devices, and learn how to use them to obtain correct measurements, each with correct precision. A metric ruler will be used to measure length in centimeters (cm).

This is a problem-based learning (PBL) group jigsaw activity. The scenario is:
Students are employees of a unit of the United Nations responsible for coordinating disaster relief after a major disaster (the 2004 Asian Earthquake and Tsunami) occurs. The agency needs to understand the situation in each country so that it can coordinate the work of various governments and nongovernmental organizations (NGOs) working in the affected area.

Students are divided into Expert Groups (related to academic specialties such as Economics, Medicine, Political Science, Earth Science, etc.) and spend several days researching their topics. Students are then reassigned to one of seven or eight Country Groups, based on the countries most affected by the disaster. Each country group needs someone representing each expert group. In the scenario, these groups correspond to task forces that must determine what the situation is in each country and try to assess the current need for international assistance.

Students research their country, using internet resources, especially the CIA World Factbook and ReliefWeb, the information coordination website of the United Nations. At a large-group roundtable discussion, each group presents what it has found about its assigned country. As a final product, each student writes an individual report summarizing findings and making recommendations for disaster assistance.

In this multi-part activity, students study seismograms from 3 different seismic stations recording the magnitude 9.0 Sumatra earthquake of December 26th, 2004. By comparing the arrival times of the P and S waves on each seismogram, students determine the distance from the epicenter to each station. Using that data, they can accurately map the location of the epicenter and the precise time of the earthquake. After locating the epicenter, students calculate the position of the tsunami generated by the quake at one hour intervals. From those determinations, predictions are made about how much time people had before the tsunami crashed onto their shores. Finally, students investigate some of the ways people can lessen the impact of the next great tsunami.

Deze vraagstukkenbundel is bedoeld als oefenmateriaal bij het bestuderen van de basiscolleges Fysische Transportverschijnselen, zoals die aan de TU Delft worden gegeven. De vraagstukken zijn afkomstig uit oude vraagstukkenbundels en uit recente tentamens. Wij hebben de formulering van veel van deze vraagstukken herzien.
Vooral door de vraagstukken in meerdere onderdelen te splitsen, hopen we aan te geven dat een stapsgewijze aanpak, veelal gebaseerd op één of meer balansen, een bruikbaar recept voor het oplossen van de opgaven is. Overigens is deze splitsing bij lang niet alle opgaven doorgevoerd om aan studenten de gelegenheid te geven juist dit moeilijke facet zelf te oefenen.

This activity uses data collected from DART (Deep-ocean Assessment and Reporting of Tsunamis) stations in the Pacific following the 2011 tsunami generated off the coast of Japan. Students are required to map the wave front after 5, 10, and 15 hours to better understand the speed and propagation of the tsunami wave.

This exercise uses the example of the March 28, 2014 M5.1 La Habra earthquake to teach about earthquake risk and resilience in southern California. Students will examine seismic waveforms recording during the earthquake, as well as read reports from scientific agencies and news outlets to answer basic questions regarding earthquake risk and resilience.

"The Journal of Materials Research is proud to announce the 2019 Gordon E. Pike JMR Paper of the Year Award. This award recognizes excellence in advancing materials knowledge through written scholarship. This year’s honors go to a team of researchers from China and the US for their report on a new form of flexible and rechargeable supercapacitor wire, which was published in the September 14, 2019 issue of Journal of Materials Research. With the rapid growth of portable and wearable electronics, researchers face many important challenges. They’re tasked with fabricating devices that are smaller, lighter, and more flexible than ever—all while delivering the same or higher levels of performance. Wire-shaped supercapacitors are among the most promising technologies developed to address these challenges. These flexible devices store and deliver energy in the form of tightly wound fibers of electrochemically active materials, such as carbon nanotubes..."

This interactive addresses the question if we can reduce CO2 emissions by 20% of 1990 levels and help avoid dangerous climate change? Users of this interactive can manipulate changes to various sources and uses (supply and demand) of energy with the goal of reducing C02 emissions in Great Britain by 80% in the year 2050.

This NOAA visualization on YouTube shows the seasonal variations in sea surface temperatures and ice cover from 1985 to 2007. The visualization is based on data collected by NOAA polar-orbiting satellites. El NiÃo and La NiÃa are easily identified, as are the trends in decreasing polar sea ice.

"Climate change is altering our world as we know it. Unfortunately, there’s no one-size-fits-all solution for making our environment resilient. From planners to scientists to farmers and ranchers, the lens through which climate change is viewed is dynamic. So how can anyone plan the best course of action with the best available data? Researchers led by Aavudai Anandhi at Florida A&M University might have just the right tool for the job. Their evidence-based approach combines three climate research methods to tailor action plans to the needs of a given ecosystem—whether that’s an entire country or state, or a single community, and whether for now or for the future. The approach begins with gathering evidence of climate change over a geographical region—the state of Florida for example. That’s done by pulling from trusted research to understand how factors like temperature or rainfall have evolved or are projected to evolve over time..."

"Climate change is altering our world as we know it Despite general guidelines for mitigating harmful changes Climate change affects different areas in different ways And those effects aren’t always clear Now, a new evidence-based tool could provide the resolution to tailor plans of action around the globe It starts with a meta-analysis that gathers climate change data for a given ecosystem That data provides the input needed to draw conclusions about future climate trends, or scenarios Such as increases or decreases in temperature The effects those changes are likely to set in motion are then linked together in a causal chain Which can reveal how crops, natural resources, or animal species will fare amid climate change Although the tool becomes limited when data for a given area are scarce It could be a powerful new way to develop custom-made plans for fighting climate change.."

On Triton, Neptune's largest moon, seasons last an average of 40 years, complete with nitrogen snow. Here's how Triton's summer solstice compares to Earth's.

On field, students have to image a given asteroid on two consecutive nights, producing two sets of images obtained over 10-15 minutes, each set separated by about 4-5 hours. In class, students have to process the images in order to measure the observed diurnal parallax and then determine the corresponding asteroid distance.

This course is an in-depth adventure through the molecular mechanisms that control the maintenance, expression, and evolution of prokaryotic and eukaryotic genomes. Through lectures and readings of relevant literature, students will explore gene regulation, DNA replication, genetic recombination, transcription, and mRNA translation. The quizzes are designed to build students’ experimental design and data analysis skills.
