Education in Germany — Bildungsbericht - EN

It can only take into account current problems in the development of education to the extent that reliable data have been ascertained. The core set of indicators remains the same in each report, hence a comparison of developments is guaranteed while the accentuation differs. Educational reporting receives its specific informative power from this consistency. Moreover, each volume includes further indicators for additional subject areas. I found that the knowledge that I had acquired and, moreover, the qualities as a student that I developed as well as the maturity I had gained, positioned me differently compared to the rest of my classmates.

I am working in Lysine production through bacterial fermentation. This is a well-known process around the world; however, we have a different approach and it already has intellectual property. Argentina is a food producer; however, it does not produce the required supplements to enrich the cattle food. Our project can provide those supplements making food production cheaper and creating an inexhaustible source of food enrichment. The first time I inoculated the medium with the lysine producer bacteria. I was very nervous and excited at the same time. I even texted my mom to tell her as a joke that my little babies were growing.

Chlorine trifluoride

Even though the formulation of the medium was the most important part, the bacterial growth was the most decisive stage. I was about to find out if the formulation was correct. So, a day in my life starts at am when I get up and start to prepare to go to university.

I take a bus and a subway which usually takes me an hour. Then I get to University and start my classes. At hrs I start working at the laboratory, I check on the bacterial growth and the Lysine production. I answer some emails and work on some projects. When I come back home I try to go for a run or to take a gym class. I find it very relaxing.

At the end of the day, I study for my classes and complete course assignments. When I am not in the laboratory or taking classes I really enjoy going to food truck fairs with my mom or baking for my family. I also like taking dance classes and running because I end up very relaxed and with a clearer mind. I think that the most important thing for a woman interested in science is never underestimating herself. Other times, I am really lost with my investigation or I get frustrated with grades after extended periods of study but I surround myself with people that really support me and remind me of how much I have achieved and how much I love what I do.

I think that a lot of research is being done in those areas and it is probable that the next great breakthrough will go in that direction. From my point of view, there should be more encouragement for little girls. Enjoy the interview with Julie and get inspired. Julie L. Nanomaterials have garnered intense interest in the scientific community, due in part to their unique shape-, size-, and composition-dependent properties, and emerging technological applications that leverage these properties require nanomaterials with very specific architectures and well-defined characteristics.

Colloidal synthetic methods are among the most effective for delivering high-quality inorganic nanomaterials with desirable properties in high yield. However, the complexities of solution-based chemistry limit the ability to predict and rationally target desired products, rendering some materials and morphologies of interest inaccessible.

Her work has focused on developing new synthetic and post-synthetic modification strategies in order to produce inorganic nanomaterials with precise control over product morphology, elemental composition, and crystal structure in a variety of material systems. I have always had an interest in problem solving and puzzles — I love a challenge, regardless of scale.

When I came up against my first chemistry class in high school, thinking about the world on a molecular level intrigued me, and I was hooked. To me, the chemical discipline represented solving some of the most complex and intriguing problems in the world, except that the answer was previously unknown. This was exciting to me as a young person, and the passion only deepened through higher-level study of chemistry through college, and now well into graduate school. I have been fortunate enough to benefit from a number of fantastic mentors and role models, scientific and otherwise, throughout my life.

My first and best role models have been my parents. Through a strong work ethic coupled with the highest value placed on integrity and respect for others, they have demonstrated to me what success in life looks like which is not specifically linked to career success. Academically, I am grateful to have benefitted from and been inspired by too many people to name in this discussion, so I will name just two: my current graduate research advisor, Dr. Raymond Schaak, and my first research advisor as an undergraduate, Dr. Richard Schaeffer. These two have been phenomenally encouraging to me, helping me to develop and to think creatively as a scientist, while giving me the space to work independently on projects that I have cared about.

Beyond that, they have modelled how one can balance the demands of a career in chemistry with other priorities in life. Conversations with these two have helped me to think broadly about the world and my place in it, going far beyond the expectations I could have asked for from an academic advisor. During my second semester as an undergraduate, I began to do research for the first time… I was enthralled by the challenge of research on the cutting edge of science. Research gave me an opportunity to think creatively about the world and the ways in which it works, and my advisor Richard Schaeffer gave me ample space to explore and problem-solve independently.

Like many aspiring U. As a student coming from a small undergraduate institution, this was my first opportunity to do research full-time, working alongside graduate students and primarily research-active faculty members. As such, this experience was amongst the most formative of my young life as a chemist, igniting a passion for academic research and scientific problem solving on the highest level that will never be quenched.

Even though significant language and cultural barriers existed between the French research group and myself, we forged relationships and collaborations through the common language of chemistry. This is where I first understood and appreciated the international impact that work in science can have: increasingly, we are participating in an endeavour that transcends our national and cultural boundaries, aided by the ease of communication and collaboration.

It was and still is incredibly exciting to me to contribute, in some small way, to something much greater than myself. These experiences propelled me into graduate school, beginning in the summer of , where I have been ever since, and will continue to motivate me as I move into the next stages of my career. By using a lower-temperature, solution-based cation exchange method, we can transform a performed material template into a material with targeted composition.

Interestingly, these transformations can be accomplished with the retention of some qualities of the template material, including features of the original crystal structure, circumventing some of the primary difficulties encountered in traditional solid-state chemistry. Using this approach, we have been able to target and isolate some unusual crystal structures in a predictable fashion, which begins to point towards the ability to generalise these approaches for polymorphic structure targeting in solid-state chemistry.

I think the most exciting thing about chemistry and science in general is that the great breakthroughs can be serendipitous and unexpected. In different ways, I have found pride in sharing my work with others. Outside of my lab or the community of solid-state chemists, there is something really exciting about communicating the major points of my science to non-technical audiences in a way that appeals to them without oversimplifying the science behind it , in formal presentations and informal conversations.

Additionally, I have found great satisfaction and pride in seeing some of my efforts come to fruition in published form. Getting to a paper is a grind — it represents many hours in lab and many, many failed experiments, significant data analysis and interpretation, as well as the actual time spent writing the manuscript and putting together figures and data in a way that communicates the significance more broadly. It is exhilarating to contribute to the scientific community, even in very small ways. To merge my passion for chemistry and my desire to engage others in STEM, I plan to pursue an academic research career after completing my graduate work.

I look forward to leveraging my career to help bridge the gap between technical and non-technical audiences and to increase scientific literacy at all levels of academia, politics and normal life. Thus far, I have observed and begun to appreciate the unique set of opportunities available to academic scientists: engagement with top-calibre colleagues, students and mentors, involvement with a built-in community of equally passionate researchers, opportunity to converse and collaborate across disciplines and institutions, and utilisation of cutting-edge instrumentation and laboratories.

Leading scientists in top academic institutions enjoy the ideal setting for making discoveries, establishing meaningful collaborations and mentoring future generations of scientists. For an ambitious and creative scientist, academic research positions provide the latitude and flexibility to innovate, the environment to pursue individual research interests sometimes several different ones , and the opportunity to truly impact the scientific world and the world at large. I enjoy traveling to new places or familiar ones , outdoor activities, reading, board games, and spending time with family and friends.

I also make some attempts to cook, though I have found that synthetic skills in chemistry do not directly translate to cooking skills although it feels like they should. Although we live in a world of instant gratification and quick answers, progress in science is often quite slow.


It requires a significant investment of time, energy and thought, and even with this discipline, projects stalling or hypotheses failing is inevitable in these disciplines. This can be discouraging to anyone, but particularly to young scientists. Eventually, progress is made: an interesting discovery, fresh eyes to interpret formerly frustrating results, or new ideas and hypotheses that can be tested and proven true, but this takes time.

My advice is to keep pushing towards the goal of understanding, and to stay positive — try not to let temporary frustrations get in the way of that. I would encourage young women in particular to not be intimidated by male-dominated academic science. If you want it and are willing to work hard, you are capable of achieving every success in science.

As a materials chemist, however, I think some of the scientific discoveries with the potential for the greatest impact on society will come from the development of new materials. We should continue to reach out to and encourage aspiring scientists as children and teens, and at the undergraduate level. This is a difficult question, and one that I think rightly is starting to be addressed at every level of academic training and careers. I think that we, as a community, are taking steps in the right direction towards an academy that looks more representative of broader society including more women and other under-represented groups.

While progress is good, this process will take time! We should continue to reach out to and encourage aspiring scientists as children and teens, and at the undergraduate level, and help to change the perception of what a scientist looks like and does. At the graduate level, mentorship is extremely important, as learning from the mistakes and triumphs of others who have gone before you is valuable for making informed decisions about your career and basically everything else. Then Steger asks: For what did you get your Nobel Prize?

Each laureate sketches his or her answer, following the only guidelines to make the sketch big and use multiple colors. The whole process takes about 20 minutes. This year he photographed three laureates: Tomas Lindahl , Bernard L. Feringa , and Jean-Pierre Sauvage. Once Steger presented his challenge, we left Sauvage alone with the paper and crayons, listening for several minutes from the hallway to crayons clicking on the desk, a sound similar to that of chalk on a chalkboard. Steger and I whisked Sauvage down the hall to a makeshift photo studio to continue the explanation.

Between shutter clicks, Steger asked Sauvage to demonstrate the molecular motion with his hands. Credit: Volker Steger. When Anthony J. Leggett wanted to twist his arms to show the atomic arrangement that allows for superfluidity, he asked Steger to tape the sketch to his body. Some laureates prefer words to pictures, diagrams and physical demonstration. Robert F. Curl, Jr. Bernard J. Feringa magically suspends his sketch of the molecular motor recognised by his Nobel Prize in Chemistry. Sir Martin J. Martinus J. They are a very diverse group of personalities.

Wahrscheinlich waren aus demselben Grunde auch die Russen hinter der Rakete her, denn sie wussten durch Spionage von der Arbeit der Amerikaner. Zuerst wurden sie in Europa inhaftiert, erst am Erst begannen die USA, die etwa erbeuteten A-4 zu starten. Der erste Start fand am Laut Holger N.

Nach der Gefangenschaft schieden sich die Wege von Dornberger und den Ingenieuren. Wernher von Braun arbeitete weiter an der A Zuerst ging es darum, die amerikanischen Techniker mit der A-4 vertraut zu machen. Der Pionier Robert Goddard war im eigenen Land nie beachtet worden.

Der erste Start einer" Bumper" fand am Die Tests mit der A-4 gingen auch nach deren Wechsel nach Alabama weiter. Die letzte A-4 wurde erst am Dieser erste Flug einer Bumper vom Cape aus verlief nicht erfolgreich. Die 5 Jahre alte und 13 t schwere A-4 flog erfolgreich. Der zweite und letzte Start einer A-4 vom Cape aus am Die Redstone basierte weitgehend auf der A-4 Technologie. Der Antrieb war leicht im Schub gesteigert worden und man hatte nun eine nichttragende Struktur.

Wie die A-4 verwandte sie Strahlruder aus Graphit. Die Redstone entsprach somit in etwa der R-5 auf sowjetischer Seite. Auch der Nachfolger der Redstone, die Jupiter, basierte auf der A Die Redstone flog erstmals am Sein Nachfolger in Huntsville wurde Dannenberg. Dannenberg wurde stellvertretender Leiter der Saturn 5 Entwicklung.

Was die NASA seitdem geleistet hat ist allgemein bekannt.

Die SS streckt ihre Krallen aus

Was noch blieb waren viele Einzelteile und der gesamte Mittelbau der Konstruktion. Weiterhin mehr als 3. Daher wurden zuerst alle noch in Nordhausen vorhandenen Bauteile der A-4 eingesammelt und in die Sowjetunion verschifft. Man begann sogar den Zusammenbau von Raketen in Nordhausen mit dem noch vorhandenen Personal, da alle Fertigungsanlagen noch da waren. Dies geschah in der Nacht vom Dazu kamen andere Personen, die freiwillig in die SU gingen. Die sowjetische Raketenforschung wollte alle Meriten selbst ernten.

Die Deutschen waren tonangebend bei dem Bau der R-1 und R-2, im Prinzip eine nachgebaute A-4 und der Vorschlag, die A-4 leichter zu bauen, den man schon bei der A-4 Entwicklung hatte, kam von ihnen. Die Sowjetunion baute zuerst einige A-4 zusammen und startete diese. Danach wurde die A-4 in Russland nachgebaut.

In der Folge verbesserte die Sowjetunion die Leistungsdaten der Rakete. Doch neue Technik bedeutet auch neues Risiko. Keine einzige der am Von den 12 Raketen erreichte nur ein Exemplar eine Reichweite von km. In den Leistungsdaten schlug sie jedes russische Konzept. Doch Koroljow wollte seine eigene Rakete konstruieren, auch wenn es nur eine verbesserte A-4 war. Die Deutschen wurden schrittweise nach Ostdeutschland abgeschoben. Die erste Gruppe im Dezember und die zweite im Juni Die dann verbliebenen hatten mit der Konstruktion neuer Raketen nichts mehr zu tun.

Sie flog erstmals am Ein kanadisches Team wollte die Rakete "Canadian Arrow" starten.
