An essential goal for physics and optical science instructors is to encourage students to find excitement and beauty in physical and optical phenomena while helping them learn the theoretical concepts and conducting experiments that can test the validity of the concepts. Such motivation largely relies on realistic hands-on lab opportunities where students can interact with physics-based phenomena as well as their corresponding laws and principles. Virtual simulation and modeling tools provide a great alternative to deliver interactive experiences when participating in physical lab environments is limited or unavailable (i.e., during distance learning due to the COVID-19 pandemic). The use of computer-based simulations can improve students' ability to make predictions and explain the phenomena practiced in the experiments. The educational value of virtual labs has been extensively investigated and reported, showing that students who use simulated equipment outperformed their peers.

In this paper, I suggest that the narrative of 2 Sam. 18:1–19:9 is read in the Korean context of being "united yet divided" through which K.P. Hong illuminates the duality between the ideal and the real in Judah's relationship with Israel. The opposition between David and Joab represents the dual circumstance of a community seeking union and simultaneously confronting division. Such duality is also observed in the distinction drawn between Ahimaaz and the Cushite. The violence in the narrative functions significantly to otherize Absalom and establish who We are. Also, the violence is intimately associated with Deut. 21:22–23 and the divine will. Therefore, a reading of this narrative through the Korean context can offer a means of resolving the difficulties of 2 Sam. 18:1–19:9 and generate the possibility of a new interpretation of the text in its present form.

One of the most profound and philosophically captivating foci of modern astronomy is the study of Earth-like exoplanets in the search for life in the Universe. The paradigm-shifting investigation described here calls for a new type of scalable space telescope that redefines the available light-collecting area in space. The Nautilus Space Observatory, enabled by multiple-order diffractive optics (the MODE lens), is ushering in the advent of large space telescope lenses designed to search for biosignatures on a thousand exo-earths. The Kinematically Engaged Yoke System (KEYS) was developed to align a segmented version of the MODE lens. A technology demonstration prototype of KEYS was built and tested using scanning white light interferometry and deflectometry. A deflectometry system was also developed to monitor the closed-loop alignment of the segmented MODE lens during its UV (i.e., Ultraviolet) curing.

With the continuous evolution of mobile device technologies, the integration of under‐display cameras has emerged as a groundbreaking innovation in the pursuit of bezel‐less and immersive visual experiences. As this technology becomes increasingly prevalent, it introduces a unique set of challenges, particularly in the realm of photography. In particular, the flare cannot be restored by conventional image processing due to saturated pixels. Therefore, a deep learning network capable of restoring such deterioration is proposed. The network is trained by a synthetic datasets generated by accurate optical simulation. However, the distortion of the camera lens distorts the shape of flare differently depending on its position in the photo, and it degrades restore quality. In this paper, we propose space‐variant CNN for solving distortion problem. [ABSTRACT FROM AUTHOR]

High precision astronomical optics are manufactured through deterministic computer controlled optical surfacing processes, such as subaperture small tool polishing, magnetorheological finishing, bonnet tool polishing, and ion beam figuring. Due to the small tool size and the corresponding tool influence function, large optics fabrication is a highly time-consuming process. The framework of multiplexed figuring runs for the simultaneous use of two or more tools is presented. This multiplexing process increases the manufacturing efficiency and reduces the overall cost using parallelized subaperture tools.

One of the most profound and philosophically captivating foci of modern astronomy is studies of Earth-like exoplanets in search of life in the Universe. The paradigm-shifting investigation described here calls for a new type of space telescope that redefines the available light-collecting area in space, far beyond what is currently possible with the 6.5 m diameter James Webb Space Telescope. The Nautilus Space Observatory, which is enabled by multiple-order diffractive optics, is ushering in the advent of large space telescope lenses designed to search for biosignatures on a thousand exo-earths.

The narrator in 2 Sam. 17.14b does not clarify Absalom's sin. To demonstrate Absalom's sin, this paper surveys the episode regarding Absalom's rebellion (2 Sam. 15.1–12) through related texts in the book of Samuel. Then it considers the stories about the two counselors, Hushai and Ahithophel (16.15–17.14). This examination reveals that Ahithophel's two counsels aim to promote the unity Absalom pursues in 15.1–12 and that this will of Absalom is frustrated by Hushai and actually by YHWH. YHWH defeats Absalom's will, just as Absalom's rebellion opposes YHWH's will; YHWH punishes Absalom measure for measure. Therefore, 2 Sam. 17.14b proves that YHWH upholds the measure for measure theological principle. [ABSTRACT FROM AUTHOR]
