Cassandra Summit 2015 - A Change of SeasonsEiti Kimura
The document summarizes Movile's big move to Apache Cassandra from relational databases for three key systems:
1) The subscription and billing system to improve performance, availability, and scalability.
2) The Kiwi user platform to reduce costs and improve throughput.
3) Distributing shared resources across a Cassandra cluster to improve scalability and reduce hardware costs.
The moves resulted in significant cost savings, throughput increases, and more scalable architectures.
- Earth rotates on its axis once every 24 hours, causing day and night. It revolves around the sun once every year (its orbit).
- The tilt of the Earth on its axis causes the seasons. Summer occurs when the location is tilted toward the sun, and winter occurs when it is tilted away.
- The moon orbits the Earth, causing phases like the waxing and waning crescent, gibbous, full and quarter moons. Eclipses occur when the moon passes between the Earth and sun (solar eclipse) or Earth passes between moon and sun (lunar eclipse).
The document summarizes what causes seasons on Earth. It explains that seasons result from the tilt of Earth's axis relative to its orbit around the sun. This causes variations in the intensity of sunlight and day length throughout the year. Specifically, summer occurs in the Northern Hemisphere when it is tilted toward the sun, and winter occurs when it is tilted away. Spring and fall seasons experience nearly equal amounts of daylight and nighttime.
This document discusses shadows, solar eclipses, and lunar eclipses. There are four types of solar eclipses: total, annular, hybrid, and partial. During a total solar eclipse, the moon completely obscures the sun, allowing the solar corona to be seen. An annular solar eclipse occurs when the moon is not large enough to completely cover the sun, leaving a ring of sunlight visible. A hybrid eclipse shifts between total and annular. A partial solar eclipse occurs when the moon only partially obscures the sun. There are also three types of lunar eclipses: total, partial, and penumbral.
Rotation occurs when an object spins around its axis, like the Earth. Revolution occurs when an object spins around another object, like the Earth revolving around the sun. The Earth's rotation causes night and day, as different parts of the Earth face the sun throughout its daily spin. The Earth's revolution and the changing angle of sunlight and day length throughout the year cause the seasons to change. We can tell the Earth rotates due to phenomena like star trails, ocean currents, wind patterns, and the movement of pendulums.
The document discusses the reasons for seasons on Earth. It explains that as the Earth revolves around the sun, the seasons change, with summer having longer days than winter due to the Earth's tilt. Some animals hibernate in winter because the days are shorter.

This document provides instructions for a study observing seasonal changes that will inform a workshop in Helsinki in May 2016. Students will keep a monthly diary recording length of day, sunshine, rainfall, temperature, and other weather data. They will also take one picture per month from June 2015 to April 2016 to document changes in views and species migration. The individual school observations will be compiled into a presentation to be sent to the workshop organizers by April 15th, 2016.
The document discusses rotation, revolution, and their effects. Rotation is an object spinning on its axis, while revolution is an object spinning around another object. The Earth's rotation causes night and day as parts of the Earth face toward and away from the Sun. The Earth's revolution and the changing angle and length of sunlight cause the seasons, with longer days and direct sun rays in summer and shorter days and indirect rays in winter. We can observe the Earth's rotation through star trails, pendulum swings, and ocean and wind currents.
The document discusses the causes of day and night, seasons, the length of a year, and the phases of the moon. It explains that day and night are caused by the Earth's rotation, seasons are caused by the tilt of the Earth's axis, and it takes approximately 365.25 days for the Earth to orbit the sun. It also notes that the phases of the moon are due to its monthly orbit around Earth and its positioning relative to the Earth and sun, which determines how much of its illuminated side is visible to observers on Earth.
An eclipse occurs when one celestial body passes between the sun and another, blocking sunlight or moonlight. There are two main types of eclipses - lunar eclipses, where the moon passes into Earth's shadow, and solar eclipses, where the moon passes between Earth and the sun. During a lunar eclipse, the moon turns red as it is illuminated only by sunlight passing through Earth's atmosphere. A solar eclipse can be partial or total, where the moon completely blocks the sun's light over a small area. Total solar eclipses are rare as the moon's shadow is small and its orbit is tilted relative to Earth's.
The document discusses various topics related to light and the sun, including:
1) Light carries both energy and momentum even though it has no mass. Light phenomena can be understood by treating light as both a particle and wave.
2) Shadows and eclipses are discussed. A lunar eclipse occurs when the earth passes between the sun and moon, casting its shadow on the moon.
3) All objects emit radiation called blackbody radiation whose spectrum depends on the object's temperature, with higher temperatures emitting light with shorter wavelengths.
The document discusses different types of rotational and orbital motions of objects in space, including the Earth. It explains that the Earth's rotation on its axis causes day and night, while its revolution around the sun over the course of a year leads to seasonal variations due to changes in the sun's angle and day length. Examples of rotation are a top spinning on its axis or the Earth each day, while examples of revolution are the Earth orbiting the sun each year or the moon revolving around the Earth.
1) The seasons are caused by the tilt of the Earth's axis of rotation as it revolves around the sun, not by variations in distance from the sun.
2) As the Earth revolves around the sun, different parts of the planet are tilted either toward or away from the sun, receiving different amounts of sunlight and experiencing different seasons.
3) The tilt of the Earth's axis remains fixed at 23.5 degrees, causing the northern hemisphere to be tilted toward the sun during northern hemisphere summer and away from the sun during winter.
1) The Earth, Sun and Moon exist in a complex system of orbits where the Moon revolves around the Earth and the Earth revolves around the Sun.
2) As the Moon orbits the Earth, the illuminated portion that we see from Earth changes in a cycle called phases, ranging from new moon to full moon and back over about two weeks.
3) Lunar and solar eclipses occur when the Moon passes between the Earth and Sun, casting its shadow on either the Moon or Earth, and can be total or partial depending on the alignment of the three bodies.
The document discusses four seasons of loneliness created by Raissa. It is a musical composition divided into four parts representing different seasons. Each season portrays feelings of loneliness through the music.
The document summarizes the motions and phases of the Earth-Moon system. It explains that the moon orbits Earth over the course of about a month in an elliptical orbit, appearing larger when closer (perigee) and smaller when farther (apogee). The changing positions result in the phases of the moon as the illuminated side facing Earth waxes and wanes over the lunar cycle. Eclipses occur when the sun, Earth, and moon align, causing the moon to block the sun during a solar eclipse or Earth to block the sun's light during a lunar eclipse.
A "lunar eclipse" and a "solar eclipse" refer to events involving three celestial bodies: the Sun ("solar"), the moon ("lunar"), and the Earth. A lunar eclipse occurs when the Earth passes between the Moon and the Sun, and the Earth's shadow obscures the moon or a portion of it. A solar eclipse occurs when the Moon passes between the Earth and the Sun, blocking all or a portion of the Sun.
This document summarizes a presentation about solar eclipses, including:
1) It discusses the mythology and beliefs around eclipses in ancient cultures like China, India, and Egypt who saw them as omens. It also covers the mechanics of how eclipses occur.
2) It provides safety guidelines for viewing eclipses, emphasizing the importance of using approved solar filters.
3) It uses computer simulations to show the partial solar eclipse of March 29, 2006 as seen from different locations, and lists some important future eclipses between the present and 2030.
There are two types of eclipses - solar and lunar. A solar eclipse occurs when the moon passes between the earth and sun, while a lunar eclipse happens when the earth is between the sun and moon. Eclipses form when the three celestial bodies are aligned in a straight line. An eclipse can be total in the umbra region of complete shadow or partial in the penumbra region of partial shadow.
The seasons are caused by the 23.5 degree tilt of the Earth's axis as it revolves around the sun, resulting in different parts of the Earth receiving more or less direct sunlight over the course of a year. Summer occurs in the northern hemisphere when its axis is tilted toward the sun, producing longer days, and winter happens when the axis is tilted away from the sun for shorter days. The changing position of the Earth relative to the sun's rays is responsible for seasonal variations in weather patterns and daylight hours around the world.
1) The document is a diary from a student's week-long trip to Paris, France for an exchange program with students from other European countries.
2) Each day provides details of the activities the student participated in, including visiting landmarks like Notre Dame, riding a bateaux-mouches boat tour, workshops on architecture, and saying goodbye to friends at the end of the week.
3) The student enjoyed learning about Paris and spending time with friends from Turkey, Greece, Poland, Finland, and other countries, but was sad to see most of them leave at the end of the week after building models of landmarks together.
An eclipse occurs when one celestial body blocks the light of another from an observer's perspective on Earth. There are two main types - solar eclipses where the moon passes in front of the sun, and lunar eclipses where the moon passes through the Earth's shadow. During a solar eclipse, the moon's shadow falls on parts of Earth and the sun appears darkened; there are three types depending on how much of the sun is covered. A lunar eclipse is visible over a larger area as the moon passes through the Earth's shadow and takes on a reddish hue. Eclipses can last up to seven minutes and a total solar eclipse occurs about every 1.5 years.
