Lounge Chair
Full text linkThe lounge chair that I have designed is based on the simple pool chair that many see near pools, but there are a few distinct differences in the lounge chair. The lounge chair has a combination of geometric and organic movement. The base of the chair has a geometric shape for support, but the top of the chair flows more organically with the body so that it is comfortable to sit in. The base and structure part of the piece is made out of elm wood and the slats, or part of the chair you sit on, is made out of pine wood. The lounge chair is held together by screws, wood glue, and staples. The lounge chair was constructed in a way in which any glue, staples, or screws would be hidden as much as possible. To finish, the chair was painted chocolate brown with a clear, water-based polyurethane finish. The paint and finish help unify and complete the artwork. The lounge chair has a modernist style and conveys movement, while also having a strong structure. The main goal of this artwork was to create a functionally simple chair with visual complexity
A Call for Extensive Investigation into Microbial Roles in Fossilization
Full text linkThe process of fossilization is a multiple-path maze that uses different roads, or various combinations of roads to take a variety of input factors such as; organisms, environment, sediment, etc., and produces a preserved record of that starting organism or trace of an organism. One of the factors that often gets overlooked in depictions or accounts of preservation is the effect that bacteria have, not only in destroying the tissue but also in preserving it through biomanipulation of the microclimate, precipitation of minerals on the soft tissue or producing a microbial film to glue an organism to the bottom of an environment long enough to be covered by sediment. (Gab et. al. 2020, Lin et. al. 2020, Janssen et. al. 2022) Determining the role of microbes in fossilization and the microbes responsible for it is both an achievable and important step in understanding the rapidity and process of fossilization. Experiments would include finding microbes that occur naturally in depositional environments that can change the chemical composition of the surrounding environment to balance the conditions needed for the preservation of the organism before it decays or is completely consumed, potentially by the same microbes. The goal of these experiments would be to observe and document the effect that the bacteria would have not only on the preservation process of the organic material but also the microbes\u27 effects on the surrounding sediment and matrix, comparing the results to known soft tissue preservation. This could be used to estimate the upper and lower time limits for the preservation of organic material. As well as the environments in which the organisms died and were buried. Due to the wide overlap of disciplines in play, it would be suggested that at least three people collaborate on these experiments, having specialties in organic or inorganic chemistry, microorganisms, and geology or fossils.

SCIENCE OF A 360 DAY YEAR
This presentation is made in hopes of finding fellow scientists, astronomers, geologists, and engineers who would like to percent a violable case for a 360 day year.
Genesis 1:14 “Let there be lights in the firmament … and let them be for signs, and for seasons, and for days, and years:” If the earth was created with a 360 day year and an exact 12 month year and an exact 30 day month then Genesis 1:14 certainly makes sense.
To make a perfect 12 – 30 day month 360 day year with a perfect full Moon the 15th of every month and a new Moon at the beginning of every month, a combination of the following scenarios would have to happen: 1) The Earth’s rotation would have to speed up to 365.24 days per year from the created 360 day year. Young Earth Creationists should not believe that the Earth was created as a molten ball of rock, and took millions or billions of years to cool to today’s temperature, rather, we should believe that the Earth was created cool and ready for liquid oceans and life. It has since cooled further and either reached equilibrium or is still cooling. This can be shown by the fact that if the Earth cooled the crust would buckle as it shrinks. There should be evidence that the crust is buckling by shrinking (mid Atlantic ridge is one example). If a spherical body experiences thermal contraction its rotation speeds up. An example is a twirling figure skater as they bring their arms in, they twirl faster. It can be calculated that the Earth would have to cool down about 1000 OC for its radius to shrink about 93 Km to speed up from 360 to 365.24 days per year (see calculation sheet). This is where a geologist is required. There must be plenty of evidence that the Earth is shrinking, or has shrunk in the past. A rapidly shrinking Earth would also help explain why the whole Earth was flooded as the ocean depths would increase. If the Earth’s interior density increased and the crusts density decreased, this would also result in a faster rotation so it was probably a combination of shrinkage and density distribution. Dr. Baumgardner’s computer modeling clearly shows how this density distribution increased with depth thus Earth’s rotation would increase (see his 1994 paper reference).
2) The Moon’s orbit would have to move out from the Earth making todays 13.3 revolutions per year exactly 13 revolutions per year. (Fig. 1) This would mean that the Moon would have to have a 391,878 km orbital radius around the Earth. (see calculation sheet)
Today’s Moon has an elliptical orbit around the Earth with the Apogee (furthest distance from Earth) at 405,500 km and the Perigee (closet distance to Earth) at 363,300 km. As can be seen at 13 revolutions per year, the distance is right in between this. Perhaps God created the Moon with a perfect circular orbit. This is where this paper needs some astronomical modelling to see what could have moved the Moon into a circular orbit. Figure 2 shows a likely possibility.
There is plenty of biblical and secular evidence that the Earth-Moon system has been altered in the past. Just to name a few (see fig 2): The flood JOSHUA’s long day Sun goes back 10 steps during Hezekiah’s reign The magi’s finding of the baby Jesus A three-hour eclipse at Jesus’s death
3) The Earth-Moon system would have to move closer to the sun; then the Moon would also get closer to a perfect 13 revolutions per year cycle. This was covered in detail in the published article (first reference below).
It’s quite feasible to believe that it’s a little bit of all the above scenarios. Astronomical orbital models are required.
