Isn't there something truly intriguing about the way someone's mind works, how a certain action in the physical world has a thread of invisible events connected to the mind. Its like the mind is the history and the concrete world is the future replica of it. Whatever is being painted on the inside takes a more lively and colorful image in the outer world. One happening on the inside is real and the other happening outside is a sheer reflection. The roots are unseen but the branches become manifest to the naked eyes. In what should I then be interested? To your body which is merely puppeting or that grand cosmos inside you? Yes, I marvel at the human mind which is the very architect of destiny. I wouldn't want to just read it. I would want to actually dip myself therein and turn it so alive that its currents could be felt across the physical world. A mega seismic wave across the earth, all commencing from a single thought in the mind!

Aww, it’s a science museum shaketable exhibit for kids. Make your own building and wreck it with an earthquake.

misci_nyCheck out miSci's newest hands-on exhibit: The MIGHTY SHAKE TABLE! Build a structure from the building blocks provided. Turn the knob to start the earthquake. During the earthquake you can vary the intensity of the seismic waves by adjusting the potentiometer. See how well your structure stands up to the mighty forces of an earthquake! The Mighty Shake Table teaches all sorts of stuff: 1. Earthquake Engineering Concepts: Engineering principles required to build a structure that survives an earthquake; foundation, height-base ratio, symmetry and truss. 2. Earth Science Concepts: Earthquakes are caused by motion on fault lines or breaks in the crust, plate tectonics and how major geological events affect the earth’s structure. 3. Science of Waves: The energy released by the movement of the earth’s plates along fault lines causes the seismic waves and what causes wave frequency to increase. 4. Scientific Testing: Analyze data from shake tests to determine similarities and differences between building designs to develop the best building practices for structures to withstand earthquakes. Plus, it's just a lot of FUN!!

Il periodo fondamentale di vibrazione

Il periodo fondamentale di vibrazione Si consideri un edificio e lo si deformi idealmente imponendo uno spostamento arbitrario in sommità. Se viene rilasciato improvvisamente, l’edificio inizia a vibrare avanti e indietro. Il tempo impiegato a compiere un ciclo completo di vibrazione, misurato in secondi, prende il nome di periodo fondamentale di vibrazione. Ogni edificio ha un periodo…

The newly discovered core at the center of the Earth has a different polarity than its surrounding core, represented by the purple lines. "For example, over the history of the Earth, the inner core might have had a very dramatic change in its deformation regime.

7.2 Magnitude Earthquake awakened the Philippines, kills at least 85.

Philippines - At around eight in the morning of October 15, 2013, a killer earthquake with a magnitude of 7.2 alarmed the residents of Bohol, destroying historic structures and leaving at least 85 dead. At that same moment, it's neighboring provinces such as Cebu, Davao, Negros, Masbate, and the entire Panay Island were also shocked by its massive intensity. Immediate reports from radio, television, search engines, and even social networking sites have spread but little do people know about how an earthquake starts and what to do in case of an emergency. When the Earth's crust releases energy, it forms seismic waves that result to earthquakes. Earthquakes are usually brought about by a geological fault rupture; however, it can also be caused by volcanic eruptions, landslides, mine blasts, and nuclear testings. The magnitude is measured by what is called a Richter scale, wherein a score of 3 and below is weak and a score of 7 and above is already considered potentially dangerous, considering the depth. On the other hand, the intensity is measured by a Mercalli scale, wherein the more shallow the earthquake, the higher the damage it can cause. To date, Japan's 9.0 magnitude earthquake last 2011 has given the most damaging effects to both nature and humanity as it has the strongest intensity. Watching video clips in YouTube gives you an idea on how bad or worse it can get when in that kind of situation. When these things happen, one must be alert. Seeing other people panic and rattling as they do, could likewise get one in trouble. Running in a wrong direction and stepping on your own foot may delay your life-saving plan. Remember to show a sense of urgency but always use your head. Move forward and keep yourself together. One must think ahead and perceive which place to go to. Is it a strong building? a mountain? Before catastrophic events happen, construct a feasible plan. Having to look back may destroy your peace of mind in reaching a safe location. Prayers help in so many ways. You might not physically save everyone you know but you can pray for their safety. Although science and religion have different concepts in every way, these misfortunate events are a reminder of God's power; wherein we are called to humble ourselves, help one another, and ask for guidance.
