Ich mochte fur die S-Bahn-Linie 6 der S-Bahn Rhein-Ruhr eine dritte Station in Ratingen vorschlagen. Sie soll den Suden und Westen der Stadt besser erschlieen und gleichzeitig eine Umsteigemoglichkeit zwischen der S-Bahn-Linie 6 und der Dusseldorfer Stadtbahnlinie U72 schaffen.

Ein von mir ausgearbeiteter Vorschlag, den S-Bahnhof Essen-Kettwig zu verlegen. Es geht darum, ihn von seinem eher ungunstigen Standort am Ortsrand in die zentrale Lage zu verlegen. Er soll sich kunftig auf Hohe der zentralen Verkehrskreuzung und innerhalb der neuen Wohnquartiere "Kettwiger Ruhrbogen" und "Seepromenade" befinden. Diese Lage ist erschlieungstechnisch und verkehrstechnisch wesentlich gunstiger, da an der zentralen Kreuzung auch der gesamte straengebundene OPNV des Stadtteils halt. Auf diese Weise wird durch die verbesserte Bus-/Bahnverknupfung ein neuer Umsteigepunkt im Essener Suden geschaffen und gleichzeitig ein Stadtteil besser erreicht. Eine gewisse Schwierigkeit bei dem Projekt stellt das zentrale Nahversorgungszentrum Guterstrae dar, was genau zwischen der Hauptverkehrskreuzung und der S-Bahn-Strecke liegt und damit genau auf der Flache, wo der zum neuen S-Bahnhof zugehorige Busbahnhof entwickelt werden muss. Ich habe das mehrmals durchgedacht und uberlegt, das Nahversorgungszentrum so umzubauen, dass es mit benachbarten Busbahnhof neu entwickelt werden kann. Im Kapitel "Gesamtkonzept zusammengefasst" werden die wichtigsten Ergebnisse der tiefgreifenden Machbarkeitsstudie auf ca. 20 bis 30 Seiten zusammengefasst. Dort kann man sich dann kurz und knapp informieren, wie die Bahnstation + Busbahnhof + P+R-Platz geplant wurde.

In Essen-Dellwig gibt es zwei recht nah beieinander liegende Bahnstationen an zwei verschiedenen sich kreuzenden Eisenbahnstrecken. Hier schlage ich vor, die beiden Bahnstationen zu einem Turmbahnhof zusammenzulegen, um so den Bahnhof als Umsteigepunkt aufzuwerten. Gleichzeitig mochte ich das Parkproblem um dem Bahnhof herum zu losen.

Cinco pensadores enormes fueron quienes permitieron que Isaac Newton descubriese las leyes que rigen los movimientos de los cuerpos en nuestro planeta y en las estrellas más lejanas. Fueron los gigantes sobre los que se alzo la figura de Newton, seis historias que el profesor Jose Maza nos relata en Bajo el manto de Urania, su nuevo libro, un profundo y conmovedor esfuerzo por sintetizar milenios de busqueda hasta dar con el hallazgo que cambio para siempre el modo de pensar nuestra posicion en el universo. Urania, la musa de la astronomia, es quien ha guiado los sueños de tantas personas en la historia y bajo su manto (el cielo), la ciencia se ha cobijado en busca de los misterios del cosmos. Acompañanos, de su mano y de la de Jose Maza, para conocer como la humanidad paso de la devota observacion de la boveda celeste a establecer las leyes que rigen sus ciclos, en este sorprendente y hermoso viaje en el tiempo y el espacio.

Biology (Greek, bios, life; logos, discourse) means the science of life. It treats of animals and plants. That branch of biology which treats of animals is called zoology (Gr. zoon, animal; logos, discourse). The biological science of botany (Gr. botane, plant or herb) treats of plants.Living things are distinguished from the not living by a series of processes, or changes (feeding, growth, development, multiplication, etc.), which together constitute what is called life. These processes are called functions. Both plants and animals have certain parts called organs which have each a definite work, or function; hence animals and plants are said to be organized. For example, men and most other animals have a certain organ (the mouth) for taking in nourishment; another (the food tube), for its digestion.

In "Being a Boy," Charles Dudley Warner presents a poignant and nostalgic exploration of boyhood, employing a richly descriptive literary style that blends humor, irony, and keen observation.

Benjamin Franklin, one of Americas founding fathers, was not only a statesman and an inventor but also an enthusiastic scientist. His profound interest in natural phenomena was influenced by his upbringing in a Puritan household where curiosity was encouraged. His involvement in the early experiments with hot air balloons demonstrates his pioneering spirit and commitment to public education, as he sought to make scientific knowledge accessible to all. Franklins scientific endeavors often arose from his relentless quest to understand and harness the natural world around him. This enlightening work is a must-read for anyone interested in the history of science and technology or the life of Franklin himself. It offers a fascinating glimpse into the mind of one of historys greatest thinkers, inspiring readers to embrace curiosity and exploration in their own lives. Discover the exhilarating dawn of ballooning and how one mans passion for discovery could inspire generations to come.

Benjamin Franklin, Self-Revealed is a biographical and critical study on Benjamin Franklins life and work mostly based on Franklins own writings. Benjamin Franklin (1706-1790) was an American polymath and one of the Founding Fathers of the United States. Franklin was a leading writer, printer, political philosopher, politician, Freemason, postmaster, scientist, inventor, humorist, civic activist, statesman, and diplomat. As a scientist, he was a major figure in the American Enlightenment and the history of physics for his discoveries and theories regarding electricity. As an inventor, he is known for the lightning rod, bifocals, and the Franklin stove, among other inventions. Franklin earned the title of "The First American" for his early and indefatigable campaigning for colonial unity, initially as an author and spokesman in London for several colonies. As the first United States ambassador to France, he exemplified the emerging American nation. Franklin was foundational in defining the American ethos as a marriage of the practical values of thrift, hard work, education, community spirit, self-governing institutions, and opposition to authoritarianism both political and religious, with the scientific and tolerant values of the Enlightenment.Contents:Franklins Moral Standing and SystemFranklins Religious BeliefsFranklin, the Philanthropist and CitizenFranklins Family RelationsFranklins American FriendsFranklins British FriendsFranklins French FriendsFranklins Personal CharacteristicsFranklin as a Man of BusinessFranklin as a StatesmanFranklin as a Man of ScienceFranklin as a Writer

Nacido en Turín (Italia) en 1875, el matemático Beppo Levi pasó la mayor parte de su vida en su país natal, donde fue profesor en las Universidades de Cagliari, Parma y Bologna.

El doctor Robert Lanza propone en este libro una perspectiva nueva: nuestras actuales teorías del mundo físico no funcionan, y no será posible hacerlas funcionar mientras no tomen en consideración la vida y la conciencia. Sugiere que la vida y la conciencia son absolutamente fundamentales para poder comprender el universo, en lugar de tratarse de una consecuencia tardia y secundaria, manifestada al cabo de miles de millones de años de procesos fisicos inertes. Y esta nueva perspectiva es lo que el llama Biocentrismo. Es una perspectiva ciertamente revolucionaria, aunque fuera adoptada por eminentes pensadores de todos los tiempos, desde Heraclito hasta Nisargadatta, pasando por Ralph Waldo Emerson y Thoreau.
