很想知道高维空间是怎样的

物理学认为高维坍缩成小尺度了 是什么意思 理解不了?

还有就是二元方程用平面 三元方程可以用立体

多元方程怎么用几何表示?

有人说人类的大脑是三维结构的无法想象出四维,这有什么关系嘛?理解不了

还有生活中有没有体现高维的东西?

我说:

0. 教学是线性的(书是字符 一维的, 老师讲课 一维的, 文章一维的)

1. 人类智商低 (初中 教学只能教到二维)

2. 学的不够(在高中期间 大量的升维 思维练习 , 数字化, 抽象化 )(楼主在这里掉队了)

3. 知识被垄断了( 大学学习的高数 可以简单把三维变方程,用方程变换 来进行思考, 线数把方程 维度无限推高) ;

再看一下下面的代码..............

基本是如何接手这样的代码呢?

$goods = M("SightGoods")->field('id')->where(array('sight_id'=>$id))->select();        if($goods){            $ids = array();            foreach ($goods as $v) {                $ids[] = $v['id'];            }            if(count($ids) > 0){                $orderWhere['gid'] = array('in',$ids);                $orderWhere['comment_status'] = 2;                $orderWhere['goods_type'] = 'sight';                $orders = D('SightOrderView')->field('id')->where($orderWhere)->select();                if($orders){                    $oids = array();                    foreach ($orders as $v) {                        $oids[] = $v['id'];                    }                    if(count($oids) > 0){                        $page = $page-1;                        $pageCount = 10;                        $limit = $page*$pageCount.",".$pageCount;                        $comment = M('OrdersComment')->where(array('oid'=>array('in',$oids)))->limit($limit)->order('create_time DESC')->select();                        if($comment){                            foreach ($comment as &$v) {                                $user = M('Users')->field('mobile,openid,nickname,email,img,sex,ind_signature')->find($v['uid']);$user['img'] = $this->eve->arrangeUserImgPath($user['img']);                                $v['user'] = $user;                                $imgs = M('UserAlbum')->field('image_path')->where(array('obj_id'=>$v['id'],'image_type'=>1))->select();                                $images = array();                                if($imgs){                                    foreach ($imgs as $img) {                                        $images[] = $this->eve->arrangeUserImgPath($img['image_path']);                                    }                                }                                $v['images'] = $images;                            }                            $this->apiRetrun(1,'ok',$comment);                        }                    }                }            }        }	$this->apiRetrun(0,'no data');    }

这是一个人类典型的多维度思考方式的自然体现

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Apr 17, 2025 am 12:06 AM

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values ​​to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
