介绍有关木星哥知识

介绍有关木星哥知识

木星是太阳系里最大的行星,距离太阳第五近。木星的正面寓意包括幸运乐观积极发展、大智若愚宽容慷慨和真诚高尚道德。 其负面寓意涉及放纵浪费和盲目固执虚假 。以下介绍一些有关太阳系里木星哥的科学知识。

木星虽是一个巨大的气态体,可它在太阳系里自转最快。木星绕轴自转一圈仅需9.9小时左右。这意味着木星的一天相对地球的一天短得多,极快的自转导致它在赤道附近明显隆起,看起来如一个橙子。木星可能在下钻石雨,甲烷在高压下能被压成钻石晶体。科研人员们推测,木星和土星内部可能真的在下钻石雨。木星的磁场很恐怖,其磁场是地球磁场的万倍以上。如果人类靠近,电子设备可立刻失灵。它的磁层大到能把太阳装进去。它不仅捕捉了大量带电粒子,有致命辐射,还产生了一场壮观的极光,木星的极光相对地球的极光能量强一万倍,且永远不停止。地球的极光来自太阳风,可木星除了太阳风,还有它的卫星,特别是木卫一埃欧喷出的火山物质被磁场捕获,沿磁力线旋转坠入木星大气,产生了持续不断的强大极光。

太阳差一些有个木星兄弟。木星包含90%氢,其它是氦,这和太阳极其相似。如果木星的质量是目前的90倍,那么它的核心压力和温度足以点燃氢,产生核聚变,让木星火了变作一颗恒星,可目前的木星被天文学称作失败的恒星。

木星海洋是金属氢。在木星厚稠的氢氦大气层下,其压力是地球大气压的百万倍以上。在这极端压力下,氢分子被分解作原子,电子被压得游离出来,变作了液态金属氢。这是一种在地球上无法存在的物质,它如金属一样导电,是木星超强磁场的来源。科研人员们估计,这片金属氢海洋可能相对整个地球还重。

人们无法在木星上登陆。木星没有固体表面,如果人试着站在木星上,只可能不断地向下掉,木星内部简直是人间地狱,人能被越来越大的温度和压力直接压碎。

由于木星巨大的引力和质量,它常被视为太阳系的守护神。它能通过巨大引力改变或吸引彗星和小行星的轨道,让它们被弹射出太阳系或吸其入木星自身,木星在一定程度上帮助了地球减少被内太阳系天体撞击的风险。可有人同时认为,地球也有可能被木星弹射出的内太阳系天体撞击,所以木星既是地球的保镖,又可能是地球的潜在元凶和危险制造者。

木星有超多卫星,目前已知有95颗卫星,它好似一个微缩迷你太阳系,其中的伽利略卫星 - 埃欧、欧罗巴、盖尼米德和卡利斯托最著名。有的卫星可能藏着海洋,甚至生命条件。例如卫星木卫三盖尼米德是太阳系里最大的卫星,科研人员们认为,在木卫三里隐藏着一个巨大的海洋。木星有一个著名史诗级的风暴眼,风速可超过 500公里/小时,此反气旋风暴已在木星表面肆虐了至少 350年。更令人吃惊的是,它的大小以前能装下三个地球,虽近年来它似乎在逐渐缩小,可仍然能放下一个地球。

QUOTES FROM THE BOOKS OF JOHN RONALD REUEL TOLKIEN 

(I appreciate Wikipedia for providing the above picture. Please let me know if it is against copyright.)


The world is full enough of hurts and mischances without wars to multiply them.

There are some things that time cannot mend. Some hurts that go too deep.

There is nothing like looking, if you want to find something.

It is useless to meet revenge with revenge; it will heal nothing.

It's the job that's never started as takes longest to finish.

No Victory without Suffering.

Where there's life there's hope.

Deeds will not be less valiant because they are unpraised.

False hopes are more dangerous than fears.

THE PRINCIPLES AND THEORY OF MONTESSORI EDUCATION

THE PRINCIPLES AND THEORY OF MONTESSORI EDUCATION

(I appreciate Confinity for providing the above picture. Please let me know if it is against copyright.)

The principles of Montessori education were developed by Doctor Maria Montessori over many years of experimentation and observation. They are based on respect for students’ learning process. From the beginning, Doctor Montessori based her work on her observations of kids and experimentation with the learning space, materials, and lessons available to them. She opened her first classroom, the Casa dei Bambini in a tenement building. The classroom was established to serve underprivileged kids who many thought were unable to learn. She frequently referred to her work as scientific pedagogy. Montessori education is based on a model of human development. The Montessori Theory is an educational approach that emphasizes individualized instruction and self-paced learning.

Respect student

This involves respecting the uniqueness of every kid - their choice of their own work, their interests, their movement, correction of their own mistakes, and their own work pace. Montessori educators work and interact with children from a place of genuine respect.

Individualized learning

Montessori learning programs are personalized to each child based on their unique stage of development, interests, and needs. Lessons with the Montessori materials are presented one-on-one based on each student’s academic progress. Educators track each kid’s progress and support them as they progress through the curriculum.

The absorbent mind and the Sensitive stages

Doctor Maria Montessori’s research determined that the first six years of life are the most crucial in a kid’s development. She termed it the stage of the absorbent mind to describe the kid’s sponge-like capacity to absorb information from their learning space. During this time, kids rapidly develop an understanding of their culture, and their world, and construct the foundations of their intelligence and personality. Doctor Maria Montessori also observed that students go through specific stages in their development when they are most capable of learning specific knowledge areas and abilities. She described these stages are windows of opportunity for learning. Characteristics of sensitive periods include intense focus, repetition, commitment to a task, and greatly extended time of concentration.

Independence

Montessori is an education for independence. It provides students with the classrooms, materials, and guidance to learn to do and think for themselves. It views kids as born learners who are capable and willing to teach themselves when provided with the right stimulus. The ultimate goal of Montessori education is independence.

Auto education and intrinsic motivation

One of the core principles of the Montessori Method is the concept of auto-education. It’s based on the belief that students are capable and willing to teach themselves if they are provided with interesting learning stimuli. Montessori materials were developed to meet this need and empower kids with the ability to direct their own education. Montessori educators provide the prepared learning space, guidance, and the encouragement for students to educate themselves. The Montessori approach takes the view that learning is its own reward. In the Montessori classroom there aren't any rewards for students’ learning. They derive a sense of accomplishment from completing an activity and learning to do it for themselves.

Educating the whole kid with every aspect

Montessori education is focused on nurturing each kid’s potential by providing learning experiences that support their intellectual, physical, emotional and social development. In addition to language and mathematics, the Montessori Curriculum also covers practical life, sensorial, and culture. Every aspect of kids’ development and learning are intertwined and viewed as equally important.

Prepared classroom

The Montessori classroom is a carefully prepared learning space where everything has a purpose and a place. There is a distinct sense of order that assists kids in developing logical thought processes. Within this learning space, students follow their interests, choose their work, and progress at their own pace.

QUOTES FROM THE FAMOUS SCIENTIST MARIE CURIE

QUOTES FROM THE FAMOUS SCIENTIST MARIE CURIE

 (I appreciate Wikipedia for providing the above picture. Please let me know if it is against copyright.)

I am among those who think that science has great beauty.

Scientists believe in things, not in person.

You must never be fearful of what you are doing when it is right.

Never to let one’s self be beaten down by persons or by events.

Now is the time to understand more, so that we may fear less.

One never notices what has been done. One can only see what remains to be done.

We must believe that we are gifted for something, and that this thing, at whatever cost, must be attained.
