一 | When Guddi was released in 1971, it made an instant star of Jaya Bachchan and also showed the world that the glamorous world of the movies wasn't so glamorous after all. Almost four years ago, actor Dharmendra spoke about why Guddi was made. He shared a clip from the film where Jaya Bachchan's character is seen expressing her love for him by looking at his pictures. "We made the film Guddi, to make school girls and boys aware that the film (movie camera emoji) world is all false. Don’t get carried away. But in vain. I still say there is a big difference between craze and love," Dharmendra wrote in the caption. Dharmendra played himself in Guddi while Jaya Bachchan played the role of a schoolgirl who has a crush on him. Guddi was directed by Hrishikesh Mukherjee and written by Gulzar. He had also posted a picture of himself and Bachchan and captioned it: "Barson baad..... Apni Guddi ke saath......Guddi jo... kabhi badi fan theyn meri (Years later with my Guddi who was once my big fan).....A happy news......"

The film also starred Alia Bhatt, Ranveer Singh and Shabana Azmi. He will now be posthumously seen in Ikkis, starring Amitabh Bachchan's grandson, Agastya Nanda. The veteran actor, affectionately known as Bollywood’s He-Man and Dharam Paaji, passed away on November 24 at the age of 89. His passing leaves behind an unmatched legacy of over six decades. The actor, born as Dharmendra Singh Deol, breathed his last at his residence. He was admitted to Breach Candy hospital earlier this month due to respiratory complications. Dharmendra is survived by his wife, actress Hema Malini, his first wife Prakash Kaur, and his children, including actors Sunny Deol and Bobby Deol, and daughters Esha Deol and Ahana Deol.

二 | 这些条状物被整合成大约60×60米的模块。因此,第三个小组一直在研究如何建立一个全尺寸的阵列,将数以千计的“瓦片”组合成模块,并将数以千计的模块组合成一个巨大的太阳能收集和传输阵列,面积约为9平方公里。这个小组得到的挑战是为这些模块创造超轻、超薄的空间结构,这些结构可以非常紧密地折叠起来,然后自主地展开成巨大的模块,并在阵列像飞毯一样在太空中呼啸时保持其形状和位置。这个团队已经做了一些惊人的工作;受日本折纸和卷纸的启发,他们已经设计并制作了卷曲、折叠、自组装的结构原型--包括可卷曲的接头--每平方米仅重150克。
