自我应验:为什么霍金全身瘫痪,也不寻死呢?

March 16, 20240 notesReblog

霍金患有罕见的神經元疾病,身体逐渐丧失功能。 他晚年已是全身瘫痪,无法发声,必须依赖语音产生装置来与其他人沟通。

然而,他选择了与疾病抗争,发表了黑洞理论,成为了与爱因斯坦比肩,的卓越物理学家

面对各种挑战,不论身体状况如何,我们也可以保持精神健康。 你拥有塑造命运的力量,并为自己的人生全权负责。

霍金说:「我有自由选择结束生命,但那将是一个重大错误。无论命运有多坏,人总应有所作为,有生命就有希望。」

人之所以不幸,正是因为自己选择了“不幸”,而不是因为生来就不幸,而“不幸”对你自身而言是一种“善”。

物质主义:璀璨帝国的洪永时是在自嗨吗?

March 15, 20240 notesReblog

洪先生开着豪车、戴着名表,以为别人一瞅见他,会眼睛放光,羡慕和崇拜。

然而,大部分时候,我们并不会觉得他有多酷。 相反,我们会陷入幻想:“如果我也能开这样的车,那该有多爽啊!”

换句话说,我们不是对别人感兴趣,而是对幻想中的自己,精神自嗨!

这是一些渴望名牌、奢侈品、旅行、美食… 的人,会产生的错觉。

总的来说,你喜欢物质享受,没关系。 但如果,你是为了取悦他人,那才是问题哦!

你不是你的工作,你不是你在银行里有多少钱。 你不是你驾驶的汽车。 你不是钱包里的东西。

佛陀耶稣为什么要断食呢?不会饿死吗?

March 14, 20240 notesReblog

从遗传学的角度来看,如果短期断食,真的会降低生存能力,人类的基因,早就无法存活下来了。

断食让胰岛素降低,储存的脂肪,开始燃烧成能量,脂肪酸供身体使用;而酮体成为大脑的燃料。

断食能让去甲肾上腺素增加,大幅提升警觉系统和精神注意力。 所以,断食不但不会疲累,反而会觉得活力充沛, 精神奕奕。

对于现今消费型的商业社会,当你断食的时候,餐厅、食品公司和药厂,都赚不到你的钱,无可避免地,成了禁忌。

佛陀和耶稣断食的原因,是为了精神修行,提升心灵。

而我们定期断食,不仅可以减轻身体的负担,新陈代谢加快,还能启动身体的自我修复机制,激活人体生长激素 (HGH),有助于降低慢性炎症,提高免疫力。 对于身体,生长激素能维护器官和促进生长;而且能提高大脑认知功能和专注力。 断食可以说是,保持年轻长寿的秘诀!

开始时,可以先试试168断食,确保自己的身体状况合适,才慢慢增强难度,到7天断食,为最终目标。

元认知:奥特曼和马斯克,谁是傻B?

March 13, 20240 notesReblog

埃隆和山姆在吵架。

这时候,在埃隆的眼里,山姆是个低智商。 同时,在山姆眼里,埃隆才是个彻头彻尾的傻瓜。

而旁边目睹了整个事件的詹森,觉得埃隆和山姆都不是傻蛋。他们的观点都各有道理,只是立场不同,完全被他们自己的主观情绪和脑补所影响了。

埃隆的脾气稍微有点急躁,说重了一些话,惹急了山姆,才导致了这场争吵。

显然,詹森的看法完全客观中立,不带任何情绪,更接近事情本来的样子。

我们所见所闻,可能都不是真的,因为它只不过是我们的大脑所塑造出来的世界而已。

三重脑理论:为什么马云的行为,经常不受自己控制呢?

March 13, 20240 notesReblog

明明只想刷5分钟的视频,结果一个晚上就莫名其妙地过去了

虽然经过数亿年的进化,让我们成为食物链顶端的理智脑出现了,但只负责决策和思考,也极其耗能。

而负责行动的本能和情绪二重脑,占了脑的八成,也接近心脏,可以优先得到供血。为了生存,他们迅速对危险做出反应,及时享受食物,和开枝散叶,并且尽量减少能量损耗。

理智脑就好像是公司里新来的年轻高管,有才华有远见,但是由于没有威信,做出的决策经常被无视,管不住公司里的基层老员工。

所以我们比较容易目光短浅、避难趋易和急于求成。

不过好在理智脑也像肌肉一样,遵循用进废退的原则。通过正确的方法,我们的理智脑也可以被锻炼的越来越强大。

本能脑和情绪脑相对于理智脑太过于强大,想要靠我们的意志力直接和他们对抗,无异于以卵击石。比较科学的办法是和他们和平相处,和他们沟通,不要试图和他们作对,而是通过激励让他们为我们所用。而深呼吸是唯一一个可以控制三重脑的方法。

二次投胎:要超越杰夫·贝佐斯,可能吗?

March 11, 20240 notesReblog

杰弗里,一个富二代,从一所名校毕业后,获得了父亲30万美元的初始资金创业。

另一方面,马修,一个“负二代”,由于财政压力,不得不辍学,去当一位饭店服务员,来解决生活开销。

快进到40岁。杰弗里,借助个人远见和家庭关系,他创办的公司,逐渐取得了成功,实现了可观的增长,最终决定提前退休。

而马修,在工作中受到侮辱,为了养家而苦苦挣扎。

这种鲜明的差异,并不是马修不"努力",因为他每天的工作时间是杰弗里的两三倍。尽管如此,马修终身都无法积累30万美元。

“马修应该怎么样改变自己的命运呢?”

当下: 马斯克问上帝,什么是我们真正所拥有的?

March 11, 20240 notesReblog

有一天,上帝走到一个人的面前,手里拿着一本大大的书,说:“孩子,该离开了。”
那人问:“这么快?书上有关于我过去的财富和记忆吗?”
上帝笑笑说:“不,亲爱的,过去只是你脑海中重构的人生。”
那人再问:“书是不是写着我下一世的事情呢?”
上帝解释:“不,未来还没到,说不定永远也不会到。”
那人猜:“那书里应该有我的灵魂吧!”
上帝回答说:“抱歉哦,现在你的灵魂是属于我的了。”
那人接过书,打开一看…
书里是一片空白!
他疑惑地问:“那我是不是什么都没有呢?”
上帝微笑着说:“不不不,亲爱的,当下的每时每刻都是属于你的哦!”

生命短暂,我们不能活在过去,但未来也是以当下的形式到来。所以要快乐地活好当下哦!

奶头乐:比尔盖茨如何让我们满足于平凡堕落?

March 11, 20240 notesReblog

全球贫富差距正在扩大,大佬们为了应对底层的不满,简单地给我们嘴里塞一个奶嘴。

转移我们的注意力,麻痹我们的认知能力,让我们对当前的状态感到满足。

这包括垃圾食品、酒精、物质、手机游戏、虚拟社交网络、色情、肥皂剧和真人秀等大众媒体。

这些娱乐选择在我们的空闲时间随时可得,防止底层的我们觉醒,不会威胁到上层社会的利益。

这就是奶头娱乐。

我们想要的真的是我们想要的吗?

我们想要的并不是我们真正想要的,而是前20%的人想要的。 我们从小就被父母、学校、社会规范洗脑。 沉迷于即时满足(社交媒体、短视频、垃圾食品……)可能会导致冲动决策,阻碍个人成长并破坏长期目标。 通过理解并将我们的注意力转移到我们自己的愿望上,从而给我们的生活带来更有意义和更充实的结果。

Integer Programming (IP) Intro & 3 Types

May 13, 20210 notesReblog

Integer Linear Programming (ILP) is required to solve optimization problems with integer values as the solution.

Integer Linear Programming ILP

Integer Linear Programming is a subset of Linear Programming (LP). It has all the characteristics of an LP, an attempt to find a maximum or minimum solution to a function given certain constraints, except for some or all of the variables to the LP solution must be restricted to integers.

There are many events we need to solve the real world optimization problems with Integer Linear Programming, instead of Linear Programming. It doesn’t make sense to use a continuous variable to represent the number of airplanes to produce because there is no point in manufacturing a partial airplane. The production of large indivisible items is one of the use case of ILP.

Graphical Method for Integer Linear Programming (ILP)

May 13, 20210 notesReblog

Revisiting the lorry loading puzzle as an integrer linear programming problem with the graphical method.

Graphical Method for Integer Linear Programming

Consider the following problem from Linear Programming with Minizinc Introduction:

300 boxes need to be loaded and shipped to a supermarket from a warehouse. We may rent lorries that can accommodate 30 boxes and 40 boxes, costing us RM 400 and RM 500 respectively. How many lorries of each type to load all boxes while minimizing the cost?

Our goal is to minimize the cost of loading these boxes by selecting the right amount of the different lorries.

Previously from Linear Programming with Graphical Method - Part 1, we concluded that with 7.5 lorries of 40 boxes (total 300 boxes), we can load all the boxes and pay only RM 3750 (7.5 x RM 500).

Boring Notes of Linear Programming

May 13, 20211 noteReblog

Linear Programming is a mathematical technique to find the optimal value for a linear system of objective function and constraints.

Boring notes of Linear Programming

Modeling is an art, not a precise science. All mathematical models necessarily contain some degree of simplification of the real world that we are attempting to describe.

Different modelers will make different assumptions, and come up with different models of more or less precision, and certainly of different sizes, having different numbers of decision variables.

Linear Programming (LP)

Linear programming (LP) is the best known mathematical optimization technique to allocate scarce resources to competing activities in an optimal manner when the problem can be expressed with continuous decision variables, linear in both objective function and inequality constraints.

Before the computers and the optimization software are available to public, students are restricted to solving linear programming problems in two variables graphically.

Linear Programming with Graphical Method

Graphical method of linear programming is used to solve problems by finding the highest or lowest point of intersection between the objective function line and the feasible region on a graph.

Moopt School equips operational researchers with the skills to analyze, model and solve real-world optimization problems through simple terms, plenty of real-world examples and helpful illustrations.

Minizinc Lesson 16 Enumerated Type

Our analysts are working with commercial-quality products, rather than educational-level optimisation software. We believe that if we could teach them on the same technologies that they will be using in workspace, we would be doing a better job of preparing the next generation for a successful Optimization or Operations Research career.

Introduction

Traditionally businesses will focus on efficiency to differentiate themselves from competitors. This includes waste reduction, faster throughput time and better customer service. While efficiency is still important in today’s environment, it is no longer sufficient for differentiation.
